Ball screwjacks can be able to transform the rotary movement into linear movement, which is a technical development of bearing. Below come some features of ball screwjacks when comparing with slide screwjacks:

a) 1/3 times the torque of slide screwjacks

By reason of more balls are working and rolling between the screw bearing and screw nut, a more efficient working can be obtained. Thus a same working rate can be achieved by ball screw jacks at 1/3 ratio the torque of slide screwjacks, so it can save a lot in power consumption.

b) Precision assurance.

Ball screw jacks are manufactured in a sequential order by the most precise machines in Japan at the most rigorous standards; especially in the manufacturing and assembly processes, research and cutting processes, inspecting and checking processes, there is a prudent control in the environmental control in aspects of temperature and humidity. A complete assurance of precision is based on a completed quality control system.

c) Possible to work at high speed.

Due to a high efficiency and low heat emission during the working process, it is possible for ball screwjacks to make high speed work.
