Linear actuator from PI has a 52 mm positioning range
The L-239 linear actuator can handle pushing forces of up to 300 N (66 lbs). It has a positioning range of 52 mm, and the high-speed version offers maximum velocity of 50 mm/s. The non-rotating tip enables uniform motion as it prevents wobble, torque, and wear at the point of contact.
