Product DescriptionPerformance GraphBall Screw Jacks SpecificationProduct Options

Ball screw jacks feature a ball nut with integral ball bearings that circulate along the surface of the ball screw. This significantly reduces friction between the ball nut and the ball screw, resulting in greater efficiency. Ball screw jacks require up to two-thirds less input torque to move the load than similarly rated machine screw jacks. They require a brake motor or external locking device to hold position.

Both upright and inverted ball screw jacks are available to lift and precisely position loads up to 50 tons. Alloy steel input shafts, aluminum bronze worm gears and tapered roller or ball thrust bearings provide rugged reliability. Select from standard lead (WB, WBL) and high lead (HWB, HWBL) models to meet your travel speed and ball nut life requirements.

Compared to machine screw jacks, ball screw jacks:

• Require less motor horsepower.

• Allow higher travel speed.

• Provide an extended duty cycle.

Ball screw jacks are available with one of four standard screw ends or special ends to meet your requirements. Double input shafts are standard. Many options are available including oversized ball bearings, which can be specified to reduce endplay between ball screw and ball nut. All jack designs can be fitted with protective boots.
