Parker Hannifin's Electromechanical Division has launched an ultra-powerful electric cylinder that can produce a thrust as high as 44kN. Forming the latest addition to Parker's popular ET series of electric cylinders, the new ETB125 is based on an exceptionally robust design to ensure durability in high duty cycle applications. It is particularly suitable for high power automation and robotics applications demanding continuous use and minimum downtime – the design features sealed tapered roller bearings, and the drive screw nut can be re-lubricated without dismantling the actuator.

The ETB125 electric cylinder offers a choice of 24 standard stroke lengths, spanning 100 mm-2.4 m (Plate 5). Furthermore, the cylinder's recirculating ball screw drive is available with a pitch of 5, 10, 20 or 50 mm, allowing users to select the optimum characteristics for their particular application. The 50 mm pitch model, for example, can handle positioning speeds in excess of 1.3 m/s, and has an efficiency of 99 per cent. Depending upon the system configuration, the cylinders can achieve bi-directional repeatability to within ±25 microns. For maximum performance, the ETB125 is best teamed with one of Parker's advanced SM series high-power brushless servo motors, which offer exceptionally high torque and acceleration/ deceleration characteristics for their size. The motors can be mounted in-line, in parallel or in reverse-parallel with the cylinder, allowing virtually any desired orientation to be accommodated.

ETB125 electric cylinders feature ISO 6431-compliant mounting options and can be supplied in any of nine metric ISO mounting styles. There is also a choice of four different rod end configurations – including spherical eye and clevis – to further simplify system integration. The cylinders are fitted with a corrosion-resistant ground stainless steel thrust rod, and the extruded aluminium housing features integral grooves for easy mounting of limit and home switches; a comprehensive range of compatible IP67 rated Hall-effect sensors and reed switches is available.
