Linear Actuator 85615 / 85616
The Motion 85615/85616 Linear Actuator provides a miniature package for operating loads up to 100 lbs.
The basic construction incorporates the Motion Ball Screw which is a high efficiency .331 diameter Epicyclic Ball Screw with integral freewheeling at stroke ends to eliminate limit switches. Both 12 VDC and 24 VDC are available. The 85615 uses a translating tube for mounting, while the 85616 is an open screw type unit where attachment is made directly to the ball nut.
