W3202SA-2Z-C5Z5 Z-type Preload Ball Screw for CNC Machine Tools

The W3202SA-2Z-C5Z5 is a precision-ground ball screw from NSK Japan, and it is a standardized "finished shaft end". The W3202SA-2Z-C5Z5 SA type ball screw adopts a single-nut offset preload (Z) structure, which effectively reduces axial backlash and improves running rigidity and response speed. It is widely used in industrial fields with high positioning accuracy requirements, such as CNC machine tools, automated slides, laser equipment, and precision handling mechanisms.

Key Advantages of the W3202SA-2Z-C5Z5 Precision Ball Screw:

Finished Ends: Both ends have pre-machined bearing positions at the fixed and support ends according to NSK standards (typically matching NSK WBK15 series support units), eliminating the need for secondary machining and significantly shortening equipment assembly cycles.

High Rigidity and Zero Backlash: Employing offset preload (Z), it maintains excellent positioning repeatability even under frequent alternating forward and reverse rotation conditions.

High Efficiency and Low Friction: Grinded raceways combined with precision steel balls achieve a transmission efficiency typically exceeding 90%, requiring less effort and generating less heat than a trapezoidal ball screw.

Common Applications of W3202SA-2Z-C5Z5 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.
