Ball Screw Jack – JWB Series: High Speed, High Efficiency, Long Life
Ball Screw Jack – JWB Series
The ball screw jack (JWB type) uses a precision ball screw pair with circulating balls between the screw and nut. Instead of sliding friction, it operates on rolling friction
Main features of JWB gearbox
●High efficiency - Rolling friction significantly improves efficiency (92% -98%)
●High speed - much faster than trapezoidal screw jacks
●Long service life - high-quality ball screws extend their service life by 3 times or more
●High precision - suitable for precision positioning applications
●Small driving source - minimal input power generates greater thrust
Important Limitation
No self-locking – ball screw jacks cannot hold a load when power is off. An external brake or braking drive source is always required
Best Applications
JWB series is ideal for:
●High-speed, high-frequency operations
●High-performance automation systems
●Precision positioning applications
●Long-life requirements
