W3209SA-5Z-C5Z8 Machine Tool Ball Screw High-rigidity Shaft End Finished Product

The NSK W3209SA-5Z-C5Z8 is an NSK SA type shaft-end finished ball screw with a nominal shaft diameter of 32mm and a lead of 8mm. The W3209SA-5Z-C5Z8 ball screw features high rigidity, zero axial backlash, stable load bearing, smooth and low-noise operation, and excellent positioning accuracy. It meets the requirements of high-speed operation and precision transmission, and is suitable for use in high-end industrial equipment such as CNC machine tools, automated precision displacement platforms, semiconductor and precision testing equipment.

Key advantages of the W3209SA-5Z-C5Z8 SA type ball screw:

High precision and high rigidity: The C5 precision grade ensures excellent positioning accuracy and repeatability. The offset preload (Z-type) method eliminates axial backlash (zero backlash), improving transmission rigidity and response speed.

High load capacity: The large-diameter (32mm) screw combined with large-size steel balls (4.762mm) provides a rated static load of up to 40,900 N, ensuring long-term stability of the equipment under heavy loads.

High efficiency and long lifespan: The balls roll between the thread raceways, achieving a transmission efficiency of over 90%. Optimized ball circulation design and materials ensure an exceptionally long service life.

Ease of installation: The "finished-end" design means the shaft end is pre-machined to standard requirements, eliminating the need for secondary machining and simplifying the assembly process.

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.
