Inline Linear Actuator 85261 / 85262
The Motion 85261/85262 Linear Actuator is designed for those applications where the mounting envelope dictates that the motor is to be in line with the ball screw.
Motor speed reduction is through a two stage spur gear arrangement with a 10:1 or 20:1 ratio. Generally the 85261/85262 series is recommended for loads up to 500 lbs. The high efficiency .653 diameter Epicyclic Ball Screw with integral freewheeling at stroke ends to eliminate limit switches. The 85261 uses a translating tube for mounting, while the 85262 is an open screw unit where attachment is made directly to the ball nut.
