Micromech has added to its actuator range the ultra-powerful electric cylinder ETB125 that generates up to 44kN thrust and has positioning speeds in excess of 1.3 metres/second. Forming the latest addition to the popular ET series of Parker Hannifin’s electric cylinders now available from Micromech, 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 electric cylinder offers a choice of 24 standard stroke lengths, spanning 100mm to 2.4 metres.

Furthermore, the cylinder’s recirculating ball screw drive is available with a pitch of 5, 10, 20 or 50mm, allowing users to select the optimum characteristics for their particular application.

The 50mm pitch model, for example, can handle positioning speeds in excess of 1.3 metres/second, and has an efficiency of 99%.

Depending upon the system configuration, the cylinders can achieve bi-directional repeatability to within ?25 microns.

Motors can be mounted in-line, in parallel or in reverse-parallel with the cylinder, allowing virtually any desired orientation to be accommodated.

The 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.

They are ideal alternatives to hydraulic and pneumatic cylinders in high power positioning applications that demand full programmable control.

They are designed specifically to provide a long operational life with minimal maintenance; a unique anti-rotate mechanism virtually eliminates cylinder rod end-play and reduces noise, whilst the front screw-support and extra length rod-support bearings withstand side loads and prevent screw whipping, vibration and run-out.

The cylinders are rated for operation over a temperature range of 0 to 60C, with a 100% duty cycle.
