Precision Shaft End Finished Product W3214SA-4Z-C5Z6 NSK Ball Screw

The W3214SA-4Z-C5Z6 ball screw has a diameter of 32mm and a lead of 6mm. It features C5 precision and a Z-preload structure, offering high positioning accuracy, zero backlash, and high rigidity. Equipped with a ZFT external circulation nut, it supports high-speed feed and is suitable for precision transmission systems in CNC machine tools, machining centers, and automated equipment.

The SA type W3214SA-4Z-C5Z6 ball screw is a finished shaft product. Both ends of the screw have been pre-machined to standard specifications (such as support bearing seats and locking threads), allowing for direct installation without complex secondary machining.

The NSK SA-type finished ball screw, specification W3214SA-4Z-C5Z6, features the following characteristics:

① High-precision transmission: The W3214SA-4Z-C5Z6 C5 precision-grade ball screw achieves high positioning accuracy and repeatability.

② Standardized shaft end design: The shaft end is pre-machined to standard dimensions, allowing direct use with support bearings, couplings, and other components, shortening design and installation cycles.

③ High rigidity structure: The 32 mm screw diameter provides strong bending and compressive strength, suitable for medium to high load conditions.

④ High transmission efficiency: The rolling contact of the balls minimizes frictional resistance, resulting in a transmission efficiency typically exceeding 90%, smooth operation, and low energy consumption.

⑤ Low backlash performance: Axial backlash can be effectively eliminated through preload design, improving motion control accuracy and response speed.

⑥ Low operating noise and vibration: Optimized ball circulation system design enables smooth and stable linear motion.

Typical Application Scenarios

Commonly used in automated equipment requiring high positioning accuracy and high rigidity, such as CNC machine tool feed axes, precision measuring instruments, and semiconductor manufacturing equipment.
