NSK W2505SA-1P-C5Z4 SA Ball Screw 4mm Small Lead Ball Screw

The W2505SA-1P-C5Z4 is a precision-ground ball screw from NSK Japan, and it is a standardized "finished shaft end". The W2505SA-1P-C5Z4 SA type ball screw adopts a preloaded single-nut structure, which effectively reduces axial backlash and improves operating rigidity and response speed. It is widely used in industrial fields with high positioning accuracy requirements, such as CNC machine tools, automated slides, laser equipment, and precision handling mechanisms.

Key Advantages of the W2505SA-1P-C5Z4 low lead Ball Screw:

Finished Ends: Both ends have pre-machined bearing positions at the fixed and support ends according to NSK standards (typically matching NSK WBK15 series support units), eliminating the need for secondary machining and significantly shortening the equipment assembly cycle.

High Rigidity and Zero Backlash: Through the interference fit (Z) of the internal steel balls, excellent positioning repeatability is maintained even under frequent alternating forward and reverse rotation conditions.

High Efficiency and Low Friction: The ground raceway combined with precision steel balls typically achieves a transmission efficiency of over 90%, requiring less effort and generating less heat than a trapezoidal ball screw.
