W2005SA-1P-C5Z4 Ball Screw NSK Precision Shaft End Finished Products

The W2005SA-1P-C5Z4 is an NSK ball screw with a 20mm diameter and 5mm lead, featuring a precision-ground SA-grade pre-finished shaft end. The shaft end is pre-machined at the factory, requiring no further processing, and can be directly installed with a standard support unit.

The W2005SA-1P-C5Z4 ball screw utilizes a single-nut interference preload to achieve zero axial backlash. With a C5 precision rating, it features a compact structure, accurate positioning, smooth operation, and moderate rigidity, making it suitable for small to medium-sized precision platforms, engraving machines, automated equipment, and testing instruments—situations requiring backlash-free precision transmission in both forward and reverse rotation.

Key Features and Advantages of the W2005SA-1P-C5Z4 Ball Screw:

Ready to Use: The SA type shaft end is precision-machined, requiring no secondary processing by the user. It can be directly matched with NSK WBK/WBN series support units, significantly shortening the assembly cycle and reducing installation costs.

Zero Backlash High Precision: The single-nut interference preload design completely eliminates axial backlash. C5-level precision ensures extremely low positioning error, suitable for precision positioning scenarios requiring frequent forward and reverse rotation.

Compact Structure: The single-nut design saves more installation space than double-nut designs, suitable for miniaturized equipment. Meanwhile, the P preload provides sufficient rigidity to meet general load requirements.

In Stock: As a standard NSK stock item, it has a short delivery cycle, enabling rapid response to equipment manufacturing and maintenance needs.
