JWB series high-efficiency worm gear ball screw jack

JWB type (ordinary ball screw type) is suitable for high-speed, high-frequency and high-performance devices. The main components are precision ball screw pair and high-precision worm gear pair. The use of rolling friction improves the efficiency of the whole machine, and only a small driving source is needed to generate a large driving force. Compared with the trapezoidal screw, the speed is greatly improved, and it can run easily and at high speed. The use of high-quality ball screws increases its working life by more than 3 times. It has no self-locking function, it is necessary to add a brake device or select a drive source with brake.

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. Compared to machine screw jacks, ball screw jacks:

• Require less motor horsepower.

• Allow higher travel speed.

• Provide an extended duty cycle.
