SFS DIN 69051 Form B BallscrewAn SFS ball screw assembly with a DIN 69051 Form B nut, intended for CNC machinery and other equipment requiring efficient conversion between rotary and linear movement.
Add to Inquiry
DFU2505 Preloaded Double Nut BallscrewA 25 mm ball screw with a 5 mm lead and a DFU double-nut assembly. It is intended for mechanisms where direction changes must produce controlled linear travel with limited lost motion.
Add to Inquiry
SFU1204 Compact Flange Ball ScrewSFU1204-3 uses a 12 mm screw shaft with a 4 mm lead. One shaft revolution moves the nut 4 mm, giving compact positioning axes a controlled feed without requiring a large-diameter screw.
Add to Inquiry
SFE End Cap Ball ScrewThe SFE series pairs a high-lead screw shaft with a flanged nut and end-cap ball return. Each standard model travels one nominal shaft diameter per revolution, making the series suitable for

About Ball Screw
Ball screw is made of screw and ball nut. It's function is to turn the rotary motion into linear motion which is a future extension and development of ball screw. The significance of the development is to move into a rolling bearing from sliding action. With little frication, ball screw are widely used into various industrial equipment and precision instruments.
Advantages Of Ball Screws
High Reliability
THA 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 THA 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.THA ball screws have gothic arch groove profiles which allow these conditions to be achieved.
Circulation Method
Ball return tube method;Ball defelector method.
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.
Production Process Of Ball Screw
1. Polishing process before heat treatment
The technological standard of the lead screw lies in the center holes at both ends, which can prevent the end face from being damaged and lead to the accuracy of the center hole. At the same time, the hardness of the center hole should reach 58 ~ 62 HRC, and the accuracy of the center hole is the key to ensuring the accuracy of the ball screw. The adjustment process of the center hole should be arranged before the rough grinding and fine grinding processes, that is, after quenching and aging.
2. Heat treatment and straightening
During the heat treatment of the lead screw, attention should be paid to avoid bending deformation, and the straightening process should be avoided as much as possible. If necessary, thermal straightening treatment can be adopted.
3. Grind
In the method and selection of grinding, we should use different tools and methods according to the material of the workpiece, heat treatment hardness, surface roughness, particle size and hardness of the grinding wheel, rough and fine grinding and so on.
