W2502SA-2P-C5Z4 NSK Shaft-End Finished Ball Screw SA Single Nut Ball Screw

The NSK W2502SA-2P-C5Z4 is a tubular circulating ball screw with a diameter of 25 mm, a lead of 4 mm, and a total length of approximately 400 mm. It features a right-hand thread design, a C5 precision grade, and high precision, low backlash, and high-efficiency transmission characteristics.

The NSK SA type ball screw is a precision-ground standard ball screw. Its core feature is that the shaft end is precision-machined, allowing direct installation with NSK standard support units without requiring secondary shaft end machining by the user, significantly shortening the assembly cycle.

Design Features and Performance Advantages of the W2502SA-2P-C5Z4 Ball Screw

High Precision and High Rigidity: The C5 precision grade meets ISO standards, suitable for high-precision positioning requirements, and achieves zero backlash.

High Efficiency and Long Life: Utilizing rolling friction and an optimized groove design, the transmission efficiency reaches over 90%. Simultaneously, the choice of materials ensures excellent durability.

Finished Shaft Ends: The journals at both ends of the ball screw are pre-machined to NSK standards, allowing direct installation of NSK-compatible support units (such as the WBK type), saving time and effort.

Pipe-Circulating Type: The nut contains an internal circulation conduit, featuring a compact structure, low operating noise, and wide applicability.
