W2807SA-1P-C5Z5 Zero Backlash Ball Screw NSK Shaft End Finished Product

The NSK W2807SA-1P-C5Z5 is an SA-type precision finished-end zero-backlash ball screw, specifically designed for machine tools. It features high rigidity and high precision, and allows direct installation of bearings, couplings, and locknuts, significantly simplifying the assembly process.

Finished-end ball screws refer to ball screws whose ends have been precision-machined to standard specifications (including steps, threads, keyways, etc.). They can be directly used with standard support units from NSK or THK, requiring no secondary fitting, and are ready to use immediately. They are widely applicable to small and medium-sized CNC equipment, automation modules, and precision transmission mechanisms that require certain positioning accuracy and rigidity.

Features of NSK SA Type W2807SA-1P-C5Z5 Ball Screw:

High Rigidity: Preloaded design effectively reduces axial backlash and improves machine tool cutting stability.

High Precision: C5 grade precision, suitable for CNC machine tools and precision positioning equipment.

Low Noise and Vibration: Optimized circulation structure reduces operating noise and vibration.

High Load Capacity: Suitable for medium to high load conditions, meeting the continuous machining needs of machine tools.

Finished Shaft End: Standardized machining of the screw shaft end facilitates installation and shortens equipment assembly time.

Long Service Life: Utilizes NSK precision grinding and heat treatment processes, ensuring high wear resistance and reliability.

Suitable Machine Tools: Widely used in machining centers, CNC lathes, grinding machines, and automated transmission mechanisms.

The W2807SA-1P-C5Z5 NSK ball screw is ideal for equipment with combined requirements for positioning accuracy, installation speed, and space constraints:

CNC machine tools: X/Y/Z axis feed systems for small machining centers, CNC lathes, engraving and milling machines, and grinding machines.

Precision instruments: Measuring equipment, semiconductor manufacturing equipment, and industrial robotic arms.
