W2505SA-4P-C5Z10 NSK C5 Precision Ball Screw Small Lead Ball Screw

The NSK W2505SA-4P-C5Z10 is a finished ball screw from the NSK SA series. It has a screw diameter of 25mm and a lead of 4mm. It adopts a single-nut preload structure and C5-grade precision design, which has high transmission accuracy, rigidity and smooth operation.

The main features of the NSK W2505SA-4P-C5Z10 ball screw are as follows:

Core Positioning: The NSK SA series precision-grade end-machined ball screw is designed specifically for small and medium-sized CNC machine tools and precision automation equipment.

High Precision and Zero Backlash: The W2505SA-4P-C5Z10 ball screw has a precision grade of C5. The "P" in the model number indicates an interference-fit ball preload, achieving zero axial backlash, effectively eliminating reverse backlash and ensuring accurate and stable positioning.

Long Life and Easy Installation: The screw shaft undergoes precision heat treatment, achieving a surface hardness of HRC 60-65, making it wear-resistant, durable, and with excellent precision retention.

Pre-machined Shaft End: The W2505SA-4P-C5Z10 end-machined ball screw is a standardized design, with the shaft end machined pre-machined at the factory. It can be directly matched with NSK standard support units, significantly shortening the assembly cycle.

Applications of the finished ball screw W2505SA-4P-C5Z10:

Precision machine tools: machining centers, CNC lathes, grinding machines, etc.

Automation equipment: semiconductor manufacturing equipment, testing instruments, precision positioning platforms

Precision manufacturing: electronic component processing, optical equipment, medical equipment

Suitable for applications requiring high-precision positioning, especially for mass production and standardized equipment.
