Therefore, they attain high lifting speeds, longer operating time, low noise and improved efficiency. With quality Taiwan TBI ball screws, high speed screw jacks are used in applications requiring higher dynamics and higher duty cycle up to 60%. They can be driven directly by electric motor or other engines, or manually operated. The highest input speed is 1000rpm. Especially suitable for high-frequency and high-speed working conditions, the maximum lifting speed is up to 500mm/s with ball screw and 200mm/s with trapezoidal spindle.

Gear housings of JBG1 to JBG10 models are cubic design housing, compact and robust, they are made of aluminum alloy with surface oxidation treatment. Compared with cast iron gearbox, it is lighter in weight, higher in strength, and easier to dissipate heat. For heavy duty model JBG15's gear housing is manufactured from ductile iron. 

All bevel gear high speed Quick Lifting Screw Jacks are functional in every installation position and can be mounted flexibly thanks to the cubic form.
