Festo
8211891
Electric cylinder EPRF-BS-55- -
The Festo 8211891 is an electric cylinder with a ball screw featuring a size 55 frame, a 16 mm screw diameter, and selectable spindle pitches ranging from 5 mm/U to 16 mm/U. This structural design incorporates a plain bearing-guide limiting the max angle of rotation of the piston rod to +/- 0.7 degrees, an M8 or M12x1.25 piston rod thread with external or internal ends, and a reversing backlash of 100 µm. Operational parameters include a stroke length between 25 mm and 800 mm with 0 mm stroke reserve, any mounting position, servo motor compatibility, no position sensing, and a repetition accuracy of ±0.02 mm. Additional performance metrics comprise a maximum actuator speed of 3000 rpm to 3750 rpm, max acceleration from 5 m/s² to 15 m/s², max speed of 250 m/s to 1000 m/s, and a max homing speed of 0.01 m/s.

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.
