	Load capacities range from 1/4 to 100 ton Worm gear driven, incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). Worm shaft is supported on anti-friction tapered roller bearings. Drive sleeve is supported on antifriction tapered roller or ball thrust bearings. Jack housing is made of ductile iron (MJ models, 1/2 BSJ and 1/2 HL-BSJ have aluminum housings, aluminum optional on 1 ton models)

	BALL AND MACHINE SCREW SERVO-JACK™
	A Servo-Jack™ is an ActionJac Ball Screw and Machine Screw Jack with Servomotors for greater control of acceleration, de-acceleration, travel rate and positioning accuracy than NEMA framed motors. Designed to accommodate any specified coupling and motor, a Servo-Jack™ can be delivered as a complete assembly. Attach a Servo Motor to an ActionJac Screw Jack Custom Motor Adaptors available Ask to speak to an Application Engineer for support with your application.
