W3211SA-2Z-C5Z5 Ball Screw NSK Precision Shaft End Finished Products

The NSK W3211SA-2Z-C5Z5 precision ball screw has a 32mm screw shaft diameter and a 5mm lead, achieving C5 precision grade. It also features offset preload to achieve zero backlash, high rigidity, high load capacity (rated static load 56000N), and excellent transmission efficiency.

Key advantages of the W3211SA-2Z-C5Z5 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 (3.175mm) provides a rated static load of up to 56,000 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 Applications:

CNC Machine Tools: Used for precision feed along the X/Y/Z axes to ensure machining accuracy.

Industrial Robots: Used for precision transmission in joints or linear modules.

Automated Assembly Lines: Used for high-precision positioning platforms, material handling, etc.

Precision Measuring Equipment: Provides stable and accurate linear displacement.
