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.
