W2006SA-1P-C5Z4 C5 Accuracy Ball Screw SA Type for Machine Tools

The NSK W2006SA-1P-C5Z4 is a model number of the NSK SA series shaft-end finished ball screw. "20" indicates a screw diameter of 20 mm, and "4" indicates a lead of 4 mm. The W2002SA-2P-C5Z4 ball screw features a return tube structure, right-hand thread, and is characterized by high precision, low friction, and high rigidity. It is suitable for applications such as CNC machine tools, semiconductor equipment, automated positioning platforms, and precision transmission mechanisms.

NSK SA type pre-machined ball screws belong to the high-precision ball screw series for machine tools. Their features include:

The shaft end is pre-machined to standard specifications, allowing direct installation of bearings and couplings.

Suitable for CNC machine tools, automated equipment, and high-precision positioning mechanisms.

Common accuracy grade is C5.
Adopting a high-rigidity design, suitable for high-speed feed and heavy loads.

Compared to the unmachined SS series, it reduces secondary machining time for customers.

NSK SA type pre-machined ball screws are widely used in CNC machine tools, semiconductor equipment, industrial automation, new energy equipment, medical instruments, and aerospace industries. Because their shaft ends are pre-machined and can be directly installed and used, they effectively shorten equipment assembly cycles, reduce processing costs, and improve overall assembly consistency.
