Electric cylinder generates up to 44kN
thrust
Parker Hannifin's Electromechanical Division has an ultrapowerful electric cylinder that can produce a thrust as high as 44kN.
Parker Hannifin's Electromechanical Division has an ultrapowerful 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 relubricated without dismantling the actuator.
The ETB125 electric cylinder offers a choice of 24 standard stroke lengths, spanning 100mm to 2.4m.
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 1.3m/s, and has an efficiency of 99%.
Depending upon the system configuration, the cylinders can achieve bidirectional repeatability to within +/-25um.
For maximum performance, the ETB125 is best teamed with one of Parker's advanced SM series high-power brushless servomotors, which offer exceptionally high torque and acceleration/deceleration characteristics for their size.
The motors can be mounted inline, in parallel or in reverse-parallel with the cylinder, allowing virtually any desired orientation to be accommodated.
ETB125 electric cylinders feature ISO6431-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.
Parker's ET series electric cylinders are ideal alternatives to hydraulic and pneumatic cylinders in high power positioning applications that demand full programmable control.
In addition to the new ETB125 model, the ET range includes models with frame sizes of 32, 50, 80 and 100mm, as well as IP65-rated versions for use in environmentally challenging applications.
All these cylinders are designed specifically to provide a long operational life with minimal maintenance; a unique antirotation 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.
To simplify the task of choosing the best cylinder for a particular application, which can involve a considerable number of thrust and power calculations, Parker has developed an Excel spreadsheet known as Cylinder Select.
This effectively automates the selection procedure, enabling users to simply specify the required motion profile and load characteristics for their application, in order check the suitability of a particular cylinder.
The spreadsheet can be downloaded from the customer support page on Parker's website. Request a free brochure from Parker Hannifin - Electromechanical and Drives Division ...
