Compact guided electric cylinder - series ELEKTRO MULTIFIX

The cylinder in the Elektro Multifix series is an electric actuator with a guided piston rod supported by two columns sliding along bushings mounted in the main extruded and anodized aluminum body. As a result, the piston rod can withstand heavy side loads. You can choose either sintered bronze bushings with grinded, chrome-plated carbon steel rods or ball recirculating bearings with hardened, chrome-plated and grinded steel piston rods.

The axial movement of the piston rod is achieved by connecting it to a ball screw nut, which is in turn moved by a hardened steel screw, which is controlled by an electric motor.

A magnet integral with the piston rod is provided to send an end-of-stroke signal and 2 longitudinal slots are provided on the body to house Square-type sensors.

A special hole, normally closed with a tight stopper, is provided on the cylinder body to facilitate the re-greasing of the screw and the screw nut.The electric motor can be connected in line with the cylinder or by means of a gear system; in the latter case you can choose among three different configurations.

The motor can be selected from among a wide optimized range, including either STEPPING or BRUSHLESS motors.The most suitable motor drives are also provided.
When using motors other than the ones in our catalogue, we can provide special flange and joints on request.

Electric axis - series ELEKTRO SVAK

This belt-driven rodless electric actuator is characterised by the fact that the motor and reducer unit is integral with the carriage, instead of being fitted to one end of the extruded section.
This solution is known as “cantilever”. In the typical application the carriage is fixed while the extruded section moves.
The SVAK can be used either horizontally or vertically, but the most common use is in vertical applications, which explains why the motor is supplied complete with a brake that causes the axis to remain still even when it is not electrically powered.
The SVAK can be applied to the SHAK GANTRY series to obtain an X-Y-Z
Cartesian manipulator robot featuring high performance and rigidity.
The SVAK uses the universal V-Lock modular system for fixing the carriage to external auxiliaries and the various components to one end of the extruded section. The sides of the extruded section, which is made of anodised aluminium, houses two hardened and ground guides that slide on adjustable wheels that are integral with the carriage. The carriage is moved by a toothed belt, complete with a tensioning system. Guide lubrication nozzles are also provided on the carriage.
A BRUSHLESS motor with a toothed belt 1:2 gear speed reducer for the pulleys was also chosen. This design was opted for because it ensures excellent load capacities without sacrificing dynamics and the typical speed of this product. In addition to the standard drive proposed in the catalogue, it is also possible to customise the cylinder by using other motors.
The homing position is detected by an inductive proximity sensor included in the supply.
A cable guiding system with cable-carrying chain and mounting bracket is also available on request as an accessory.

Electric axis - series ELEKTRO VBK

Belt-driven rodless electric axis with load-bearing structure consisting of an anodized aluminium extruded profile and linear guide system comprising a rail and ball-recirculation pads. The motor and gearbox unit is fixed to the central body (so-called "cantilever" solution). The typical application foresees that the central body remains fixed and the extruded profile moves. The VBK can be mounted in both horizontal and vertical orientations; for example can be used as a Z axis in a cartesian portal, typically with a BK Series Gantry. Motion transmission is obtained by means of a polyurethane toothed belt reinforced with steel cables. The parabolic profile of the belt tooth ensures high efficiency, reduced noise and vibrations. The central body houses the transmission group consisting of a driving pulley and two idle rollers ("omega" configuration). The axis, which can be ordered with a stroke per mm, comes complete with an adjustable belt-tensioning system and independent channels for pad re-lubrication. Threaded and centering holes are present on the central body and on the heads allowing multiple mounting options. The extrusion has the characteristic V-Lock profile as well as an internal opening where to pass cables and pipes. It is possible to purchase the axis with or without drive. The standard drive includes a brushless motor with brake, combined with a precision planetary gearbox available in two different gear ratios. The motor unit can be mounted on either side of the central body.

Electric axis - series RODLESS ELEKTRO BK

Electric belt-drive rodless axis with a bearing structure made up of anodized extruded aluminium.
The typical V-Lock dovetail is fitted to the extruded side (opposite the slide), which facilitates the fixing using QS elements; at both sides there are grooves for the installation of the bracket fixing the proximity switch (optional), which detects the position of the slide.
The slide is moved by the polyurethane toothed belt with steel cables.
The parabolic profile of the belt tooth makes it possible to maintain a high efficiency level, contain the level of noise and vibration from transmission gears.
The axis is available in two sizes, BK-1 and BK-2.
The slide interface is characterised by the V-Lock profile complete with M5 threaded holes, pinholes and key seats, which guarantees numerous fixing options (not present in the BK-2 heavy XL version).
All the versions have in-line steel guides that are housed in an extruded structure. The BK-1 size is available in two variants: the “Medium” uses castors running along hardened and tempered guides with double-row ball bearings, and the more performing “Heavy” version consists of a guiding system with a rail and ball recirculation pads.
The BK-2 size is available in two variants, both with rail and ball recirculation pads, the “Heavy” type has two pads and the “Heavy XL” has a longer slide and four pads. In the BK-2 size, the belt has a special profile that, when coupled with the extruded profile, prevents any dirt or foreign bodies from entering inside. BRUSHLESS and STEPPING motors are available, with optional motor brake and/or built-in encoder.
The versions with a BRUSHLESS motor can be equipped with a toothed belt speed reducer or a planetary gearbox.
The electric axis can be ordered without drive or, on request, with modules for interfacing with motors available from the trade.
The motors can be installed on all the four hubs of the heads, and their position can be changed at any time, without requiring any additional operation.
Various accessory kits for the installation of a gantry system starting from one axis are also available.

Electric axis - series RODLESS ELEKTRO SK

Screw-driven rodless electric axis with a load-bearing frame made of anodised extruded aluminium, which gives the cylinder optimal torsional and flexural rigidity. It comes in two sizes, SK-0 and SK-2.
For the SK-0 size, two V-shaped guides run directly on the outer edge of the extruded section and support a moving carriage fitted with two wear-resistant acetal resin pads. The pad clearance can be adjusted by means of threaded grub screws placed to the side of the carriage that can be used to make up any play caused by wear. Due to pad support, the carriage only conveys axial forces to the feed system consisting of a self-lubricating techno-polymer nut and a lead stainless steel screw. Two slots are provided on each side of the liner for fixing magnetic sensors.
Size SK-2 features a carriage driven by two sturdy preloaded ball recirculation pads that ensure great accuracy of movement.
Threaded holes for the lubrication of the guides and the ball recirculation screws are provided on both sides of the carriage.
The carriage is driven by a system consisting of a hardened and tempered screw and a ball-recirculation lead nut. In order to reduce vibration, hence noise level, and increase the system useful life, the screw is pre-stressed with an elastic load device by means of cup springs.
The slots on both sides of the liner are provided for fixing magnetic sensors.
For size SK-2 only, the motors can be installed either in line with the liner or geared using toothed-belt transmission gears.
The carriage features an interchangeable fixing interface plate, which can be ordered with such attachments as the axial V-Lock or orthogonal V-Lock ports or the blank type for custom solutions.
Various STEPPING and BRUSHLESS motor drives are available with optional motor brake and/or built-in encoder.
This axis can also be supplied without motor drive or, on request, with modules for interfacing with motors from the trade.

Electric axis - series ELEKTRO SHAK

The cylinder structure features a sturdy anodised aluminium extruded profile to ensure optimal rigidity. The typical V-Lock dovetail (no grooves) is provided for easy installation using QS elements. The V-Lock interface with a dovetail and standard grooves is mounted on the moving plate to fix the other components using K or QS elements. The slide is moved by means of adjustable casters running along hardened and tempered guides inserted into the extruded profile, to obtain a rigid system with adjustable clearance. Guide lubrication nipples are also mounted on the slide plate. The slide is driven by a reinforced belt that is in turn operated by a pulley keyed onto the motor; a mechanical belt-tensioning system is mounted on the cylinder. Different drives are available, both brushless and stepper. The versions with a brushless motor can be equipped with a 1:3 speed gear unit, when you want to make the most of the available torque.
In addition to the standard drives included in the catalogue, custom cylinder can also mount other types of motor. The homing position is identified by a inductive sensor included in the supply.
Two different size are available, SHAK 340 and SHAK 470, with pre-set standard strokes. For each size it is possible to choose side on which to mount the motor (4 positions). A version with a smooth tree-type output, mounted in a pre-set position, is also available. The SHAK cylinder can be mounted both horizontally and vertically. With vertical installation, it is advisable to use motors with a holding brake that only activates in the event of a power failure but not when there is a motor overload. For the correct operation of the brake, it is necessary to meet the limits required by the axial load curves according to the speed. Among the accessories available there is a cable guiding system with a handy cable channel and bracket.

Electric axis - series ELEKTRO SHAK GANTRY

The gantry consists of two parallel belt-driven axes, of which one acts as drive axis (drive X-axis) and the other as driven axis (geared X-axis). Both axes are connected one to the other by means of an anodized aluminium shaft and two flexible couplings that compensate for any minor misalignments between the axes caused by the support base. The shape of both coupling and drive shaft is designed to facilitate disassembly.
The carriages of the drive axis and the driven axis (both with a V-Lock interface featuring a typical shape and grooves) move synchronously thanks to the drive shaft. On the extruded body of both axes, on the side opposite to the carriages, the typical (no grooves) V-Lock dovetail is provided for easy fixing to the support to the support structure using QS elements. On the carriages of the X-axes another SHAK electric axis (Y-axis) is mounted transversally. The motion is the same as for the single axis and has the same advantages: rigid structure, movement of the carriage with adjustable clearance, the presence of guide lubrication nozzles, the possibility of adjusting belt tensioning.
A BRUSHLESS motor with a 1:5 speed gear unit has been adopted as it ensures optimal load capacity without sacrificing the dynamic and speed performance typical of this product.
In addition to the standard drives proposed in the catalogue, the cylinder can be customised with the installation of other motors.
The homing position is identified by an inductive proximity sensor included in the supply.
Two sizes are available, SHAK-GANTRY 340 and SHAK-GANTRY 470, with standard pre-set strokes. For each size, it is also possible to choose on which side to mount the motors (right- or left-hand).
The Elektro SHAK-GANTRY was designed and optimized for horizontal installation. On request, the motors can be supplied with a holding brake, which activates only in the event of a power failure but not when there is a motor overload. For correct operation of the brake, it is important to comply with the limits required by the axial load curves according to speed. Among the accessories available there is a cable-guiding system with a handy cable channel and bracket (in the version with motors on the left-hand side).

Electric cylinder - series ELEKTRO SSC

An electric cylinder with a connection interface in accordance with ISO 15552.

The ELEKTRO SSC series differs from the ISO 15552 ELEKTRO series in some design choices, including the absence of the front and rear heads. The cylinder is available in defined strokes (different depending on the type of screw). The piston rod moves forwards by either the hardened and tempered steel screw and a ball recirculating screw nut or a stainless steel screw and technopolymer lead nut. The cylinder is equipped with an anti-rotation system that can be easily removed as required. A magnet is fitted to the piston rod to provide a limit switch signal and two separate lengthwise slots are provided on the cylinder body to accommodate the Square-type sensors. An easily removable  plate is attached to the cylinder body to facilitate re-lubrication of the screw. The cylinder is available in either in-line or geared version. The motor can be selected from among an optimized range, which includes both STEPPING and BRUSHLESS motors. The most suitable drives for the motors are also provided. Special flanges and couplings are provided on request when motors of a make or model other than those specified in the catalogue are used

Electric cylinder - series ELEKTRO ISO15552

An electric cylinder with a connection interface in accordance with ISO 15552.
The piston rod extension is controlled by a system with a hardened screw and recirculating ball screw. The piston has a guide strip calibrated to reduce to a minimum play with the barrel and hence vibration during ball screw rotation.
The cylinder can be equipped with a built-in non-rotating system featuring two opposing slides that run in separate longitudinal slots in the barrel.
The piston comes with magnets and the barrel has longitudinal slots for housing sensors. The piston rod has increased outside diameter and thickness to make it extra rigid and more resistant to radial and peak loads.

Cylinders with a flange suitable for a motor brand that is most liked by the customer are available on request. 

Electric cylinder - series ELEKTRO MINI DC

The ELEKTRO MINI DC cylinder features space-saving and lightweight design, as well as easy and immediate operation.

The piston rod is driven by a trapezoidal screw with a self-lubricating techno-polymer nut. The construction characteristics make the movement of the piston rod irreversible, thereby preventing it from rotating. The piston comes with a magnet that can be detected by dedicated sensors to be fitted to the liner edging. The system’s 24VDC driving motor comes with a resettable overload protection fuse; a version with an encoder is also available to locate the piston rod position.

The actuator is in a gear-driven version, with different gear ratios (1/12, 1/27, 1/48 and 1/108) and IP40 degree of protection.

Solutions with a trapezoidal screw are generally suitable for applications where the number of operations in a unit of time is relatively low (due to overheating of the screw/lead screw-nut assembly), the required precision is not particularly high, wear over time is minimized and high strengths and high speeds are not required all at the same time.

Electric cylinder - series ELEKTRO ROUND DC

In the ELEKTRO ROUND DC cylinder, the forward movement of the piston rod is obtained via an acme screw and a self-lubricating technopolymer nut. This piston has a guide ring that is calibrated to minimize the backlash with the cylinder liner and reduce vibration during rotation of the screw.
The piston also comes with a magnet for magnetic sensors.
The system is driven by a direct current motor available in two versions, 12 and 24VDC. The position of the motor can be controlled using an optional encoder. A resettable optional fuse can be inserted in the cylinder for motor thermal overload protection. The motor used has a planetary gearbox with a 1/13 or 1/25 ratio. Depending on the configuration (screw pitch and gear ratio), this cylinder can be either irreversible (supporting the load with the motor off) or reversible under load. Both versions are supplied without piston rod anti-rotation device, which will be provided by the customer outside the cylinder.
It is available in two versions:
- with an in-line motor, where the motor shaft is connected directly to the screw via a coupling
- with a geared motor, where the transmission of motion is ensured by three cogwheels with a ratio of 1:1.
This cylinder is designed for use with IP65 protection rating.
The solutions with the acme screw are generally suitable for applications where the number of operations per time unit is reduced; the degree of accuracy is not particularly high due to heating of the screw-leadscrew assembly; wear over time does not create inconveniences, no high forces and speeds are required at the same time.

Electric rotary actuator - series ELEKTRO RBA

Compact electric rotary actuator providing unlimited rotation angle in both directions.

Motor power is transmitted to the load by a toothed belt drive with a specific gear ratio, thereby ensuring high performance in reduced dimensions. The belt is maintained at the correct tension by an adjustable eccentric tensioner.

The driven pulley features a through-hole that allows pipes and cables to pass through to facilitate integration with other devices. The actuator can be attached onto all the surfaces of the main body by threaded holes, thereby offering multiple installation options. The rotary flange can be placed on the same side as the motor, either on the opposite side or on both sides, to meet any application requirement.

This actuator can be used either as a fixed rotary table or applied to a moving axis, like the VBK, thereby greatly increasing the range of applications. It is available in two sizes, RBA-1 and RBA-2, with or without motorization.

The standard drive of the RBA makes it possible to choose between a BRUSHLESS motor and a STEPPING motor with encoder.Both versions are available with a holding brake.In the case of the RBA-2 size, the BRUSHLESS motor is also available in version combined with a precision planetary gearbox

Electric slide - series ELEKTRO CS

Compact electric slide, equipped with a guideway and a ball-recirculating pad capable of withstanding high radial loads on the piston rod. The slide in the ELEKTRO CS series features the same technical choices as those made in the ELEKTRO SSC series in terms of extreme compactness and pure design, including the wear-resistant aluminium body. Driven by a hardened steel screw and recirculating ball screw nut, the stainless-steel piston rod is coupled, via a rigid aluminium structure, to a recirculating pad that runs along a guide rail integral with the main body. The coupling system prevents the piston rod from rotating.

A magnet is integral with the piston rod to ensure an end-stop signal, while two longitudinal slots are provided on the body to accommodate Square-type sensors.

For easy re-greasing of the screw and nut, the cylinder body comes with a special hole that is normally closed with a silencer (to ensure IP65 protection this hole must be directed to the outside).

The ELEKTRO CS series slide is available in either a standard profile version or a V-Lock interface version.

The electric motor can be either connected in-line with the slide or by means of a transmission system; in the latter case, three different configurations are available.

The motor can be selected from an optimised range comprising both STEPPING and BRUSHLESS motors.Drives most suitable for motor control are also provided. When using motors of a make or model other than those offered in the catalogue, special flanges and couplings can be made and supplied on request.
