    Electric Cylinder / Rodless / Belt-Driven / Lightweight

    Belt-driven rodless electric axis with a V-Lock interface. The structure features an extremely lightweight yet high-strength anodised aluminium extruded profile. The typical V-Lock dovetail is obtained at the base of the extruded body ensures easy installation using QS elements; at both sides there are grooves for the installation of the fixing bracket of the (optional) proximity switch that detects the position of the slide. The slide is moved by means of the polyurethane toothed belt with steel cables. The parabolic profile of the belt tooth combines with the anti-friction nylon coating to enhance efficiency, reduce the level of noise and vibration from transmission gears. The slide interface is characterised by the V-Lock profile complete with M5 threaded holes, pinholes and key seats, which guarantees numerous fixing options.Two different variants of the in-line guiding system are available: the version Medium uses casters running along hardened and tempered steel guides with double-row ball bearings running along the specific H&T steel rail; the version Heavy, high-efficiency, consists of a guiding system with a rail and ball recirculation pads.

    Pneumatic Cylinder / Double-Acting / Rodless / With Adjustable Cushions

    Rodless cylinders come in five different bores - 0 16, 25, 32, 40 and 63 mm - and the design incorporates numerous innovations.

  • Calibrated extruded anodized aluminium alloy barrel
  • Sensor slots and accessory slots in the barrel itself
  • Longitudinal seal by means of specially-shaped indeformable stainless steel strips
  • Strokes 100 to 5700 mm with 1 mm intervals
  • Adjustable integrated pneumatic cushioning
  • Adjustable limit switches and decelerations con be applied at any time
  • For this type of cylinder {size 32 and upwards), the valves can be fitted directly using the retracting sensors without requiring any intermediate brackets.
    Pneumatic Cylinder / Double-Acting / Rodless / With Adjustable Cushions

    Series PU rodless cylinders have an internal strip for longitudinal tightness made of polyurethane (PU) with a harmonic steel wire core. This solution gives excellent air tightness values. It is particularly suitable for high-speed and highly cyclical applications, even with long strokes. The external strip, which merely provides protection against of foreign bodies entry, is made of harmonic steel. The anodised aluminium cylinder liner has a T-slot on either side for housing the retracting sensors. Cylinder control solenoid valves can also be housed in these slots and secured by means of plates and screws (see page A1.48). There are plastic anti-wear guide pads on either side of the carriage to increase the load capacity. They engage V-slots in the cylinder liner. All the cylinders incorporate adjustable pneumatic cushioning. One version has hydraulic decelerators + adjustable limit switches. These can also be added at a later stage by purchasing the relevant kit. The balanced drive version avoids having to transmit transverse torques and forces to the carriage whenever the load is supported by guides outside the cylinder.

    Pneumatic Cylinder / Rodless / Magnetically-Coupled / Anodized Aluminum

    V-Lock rodless cylinders come with bores Ø 16, Ø 25 and Ø 32. Their main feature is that the carriage support has a dovetail with V-Lock grooves for mounting other components in the V-Lock family. The provision of threaded holes and centring pins allows non-V-Lock components to be fixed onto the carriage. The fixing legs also use the V-Lock system, so the cylinder can be fixed onto something else using K or QS elements. The carriage support is mounted on ball-recirculation pads that run on tempered guides and can withstand very high loads and moments.

    Electric Cylinder / Rodless / Belt-Driven / Anodized Aluminum

    Belt-driven rodless electric cylinder with V-Lock type interface. 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 stepping. The versions with a brushless motor can be equipped with a 1:3 speed gearbox, 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.

    Electric Cylinder / Rodless / Anodized Aluminum

    Electric axis without screw piston rod, with V-Lock interface. The cylinder frame is made of anodized extruded solid aluminium, which gives the cylinder optimal torsional and flexural rigidity. The typical V-Lock dovetail is provided on three sides of the channel for easy fixing with QS elements. The carriage features an interchangeable fixing interface plate, which is available with V-Lock axial or V-Lock orthogonal ports or in the blank type for custom solutions. The carriage is driven by two sturdy pre-loaded ball recirculation bearings that ensure great accuracy of movement. Threaded holes for the lubrication of the guides and 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. The screw is pre-stressed with an elastic load device by means of cup springs in order to reduce vibration and hence noise level and the useful life of the system. A series of slots for the fixing of magnetic sensors are provided on the two sides of the liner. Various BRUSHLESS and STEPPING motor drives are available with optional motor brake and/or built-in encoder. The cylinder can also be supplied without motor drive or, on request, with modules for interfacing with motors from the trade. The motors can be installed in line with the liner or geared using toothed belt transmission gears.
