Worm Screw Jacks HK series belong to trapezoidal screw jacks. They are available in a useful range up to a capacity of 100T and are competitively priced.

Screw jacks JWB (General ball screw) is suitable for high speed, high frequency and excellent performance.Main components: Precision ball screw pair and high precision worm-gears pair.

Trapezoidal acme screw jacks are popular among daily use. Its features are that  it is simple to maintain, low noise, and can work normally at high / low temperature, corrosion / explosion harsh environment,

Ball screw working principle is to turn the rotary movement into a linear motion, or linear motion into the ideal rotary motion products. So the ball screw jacks have high precision,reversible and efficient features.
