Product Description

Using the famous TBI ball screw, our worm gear ball screw jacks offer higher transmission efficiency, greater speed, longer life, and lower noise than other machine screw actuators. Especially suitable for high speed and high-frequency operation, the speed up to 6.5m/min. Ball Screw Jacks can be used individually or as part of a larger mechanical system and require less power to drive the load. Because of no self-locking function, a machine ball screw jack needs a brake motor or external locking device to hold the position.

Alloy steel input shafts
ZQAl9-4 tin bronze worm gears
Tapered or ball thrust bearings
Protective tube and bellows are available
Top plate, clevis end, thread end, plain end standard
SIJIE can customize to your specifications
