1,Intruduction

High precision low noise ERSK ball screwBall screw is made of screw, nut and ball. The function is to turn the rotary motion into liner motion, which is a further extension and development of ball screw. The significance of this development is to move into a rolling bearing from sliding action; With little friction, ball screws are widely used in various industrial equipment and precision instruments.2, Ball screw feature

High Reliability

TBI MOTION or ERSK ball screw 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 or ERSK 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 or ERSK ball screws have gothic arch groove profiles 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.

3, All kinds of ball srew series
There are many different series of ball screw shaft with nut, like SFU series, SFS series, SFI series, SFY series, DFU series, SFUL series, SFK series.Each series has its own characteristics, Let's look at the difference in appearance and characteristics.

4, Ball screw Specification
1. Cold rolled ball screw; 2. Gcr15 material; 3. High-speed operation 4. C5 C7 C10 precision; 5. No gap and preloading 6. Quality as good as TBI brand is high precision, long life use. 7. Pay more attention to before-sale, in-sale, after -sales service. 8. Manufacturer with large stock & short delivery
