Ball Screw

High Reliability

DRE 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 DRE 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.DRE ball screws have gothic arch groove profiles (Fig. 1.2) which allow these conditions to be achieved.

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.
