NSK A-series ball screw W2503SA-3P-C5Z6 finished ball screw at the shaft end

The NSK W2503SA-3P-C5Z6 ball screw is a high-precision SA-type tubular circulating ball screw specifically designed for machine tools. This model is commonly used in CNC machine tools, precision automation equipment, precision positioning tables, and other linear transmission applications requiring high rigidity, small lead, and high-precision micro-feed.

Key Advantages of the SA-type W2503SA-3P-C5Z6 Ball Screw:

High Rigidity and High Load Capacity: The SA-type design optimizes the circulation trajectory of the steel balls in the tubing, maintaining extremely low elastic deformation even under high axial loads.

High Positioning Accuracy: C5-grade precision combined with a backlash-eliminating preload design provides excellent repeatability and effectively prevents "reverse dead zones" during machine tool feed.

Elimination of Secondary Machining: As a standard pre-machined screw, both ends are typically pre-machined according to NSK standard support units, significantly shortening the assembly and maintenance cycle of equipment.

Common Applications of W2503SA-3P-C5Z6 SA Type Ball Screws:

CNC Machine Tools: X/Y/Z axis transmission for small precision CNC machine tools and engraving machines.

Precision Automation: Semiconductor wafer handling, electronic component placement machines, and robotic arm positioning axes.

Measuring and Testing Instruments: Linear drive for coordinate measuring machines and optical precision inspection stages.
