Name: Festo 556813 Belt driven linear actuator EGC-70- -TB-KF
Brand: Festo

Belt driven linear actuator EGC-70- -TB-KF

The Festo part number 556813 is an electromechanical linear axis with a toothed belt featuring a size 70 design, a 24.83 mm drive pinion effective diameter, and a 3 mm toothed belt pitch. Incorporating a recirculating ball bearing guide and an incremental linear potentiometer measuring principle, this component supports a working stroke from 50 mm to 5000 mm, a maximum speed of 5 m/s, a maximum acceleration of 50 m/s², and a repetition accuracy of ±0.08 mm with a 100% duty cycle in any mounting position using either a stepper or servo motor. Certified for explosive atmospheres with ATEX and UKEX compliance for gas Zone 1 and Zone 2 and dust Zone 21, the unit operates within an ambient temperature range of -10°C to +60°C under EPL Db and Gb certifications with Ex h IIC T4 Gb ignition protection.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
