W2003SA-1P-C5Z4 SA type C5 precision ball screw for machine tools

The NSK W2003SA-1P-C5Z4 SA type C5 precision ball screw has a 20mm screw shaft diameter and a 4mm lead. The SA type ball screw uses tube circulation and is paired with a PFT type nut, making installation convenient and operation smooth. The shaft end is pre-machined and ready for direct assembly and use.

Design Features and Performance Advantages of the W2003SA-1P-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 material selection ensures excellent durability.

Finished Shaft Ends: The journals at both ends of the 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, resulting in a compact structure, low operating noise, and wide applicability.
