Ball Screw

High Reliability
TBI MOTION has very stringent quality control standards covering every production process. With proper lubrication and use,trouble-free operation for an extended period of time is possible.

Smooth Operation
The high efficiency of ball screws is vastly superior to conventional screws. The torque required is less than 30%. Linear motion can be easily changed from rotary motion.

High Rigidity and Preload
When axial play is minimized in conventional screw-nut assemblies, the actuating torque becomes excessive and the operation is not smooth. The axial play in TBI MOTION precision ball screws may be reduced to zero by preloading and a light smooth operation is still possible. herefore, both low torque and high rigidity can be obtained simultaneously.TBI MOTION ball screws have gothic arch groove profiles (Fig. 1.2) which allow these conditions to be achieved.

Circulation Method
Ball return tube method.(V、E、S、Y type);Ball defelector method.(I、U、M、K type)

High Durability
Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience,have resulted in the most durable ball screws manufactured.
