TOSOKPrecision ball screwCharacteristics of:

(1) High mechanical efficiencyball screwHaving a high efficiency of over 90% that traditional sliding screws cannot match (Figure 1), the required torque is only one-third or less of that of sliding screws. Therefore, it is also easy to transform linear motion into rotational motion (inverse motion).

(2) The axial clearance can be adjusted. If the axial clearance of the traditional sliding screw is reduced, it becomes very difficult to retract it; Even if the axial clearance of the ball screw is reduced, smooth rotation can still be achieved. Moreover, by applying preloading, the axial clearance of the ball screw can be adjusted to 0, while improving the rigidity of the screw.

(3) Long lifespan: Adopting rolling contact, it will not wear out even after long-term use, and can maintain high precision.

(4) Precise micro transmission can be achieved through rolling contact, and the starting torque of the ball screw is small, so precise micro transmission can be achieved.

(5) High precision: The screw shaft and nut are subjected to thread grinding, assembly, and inspection in a workshop with strict temperature control.

(6) TOSOK Company has a complete quality management system and has passed ISO9001 certification for a long time. It has established a comprehensive quality management system and is committed to providing customers with satisfactory products.
