NSK W3214SA-3P-C5Z6 small lead grinding ball screw PFT type nut

The NSK W3214SA-3P-C5Z6 SA type ball screw has a 32mm shaft diameter and a 6mm lead, classifying it as a small-lead ball screw. The SA W3214SA-3P-C5Z6 shaft-end finished ball screw uses a tubular circulation design and features a PFT flange-type nut, ensuring convenient installation and smooth operation. It is commonly found in the machine tool industry.

The main features of the W3214SA-3P-C5Z6 ball screw are as follows:

① High precision and zero backlash—It achieves a precision grade of C5 and uses interference preload (P-type), ensuring zero axial backlash at the factory and guaranteeing no backlash during reverse positioning;

② High rigidity and heavy load capacity—The screw shaft diameter is 32mm, equipped with 3.969mm steel balls, and the rated static load is up to 34,700N, capable of withstanding heavy-duty cutting and frequent start-stop operations;

③ High efficiency and long service life—The ball rolling transmission efficiency can reach over 90%, and the raceway is high-frequency quenched to HRC 58~62, exhibiting excellent wear resistance;

④ Easy installation—It is a finished shaft product, with both ends pre-machined to standard specifications, requiring no secondary grinding before direct assembly into equipment.

Typical applications of the W3214SA-3P-C5Z6 ball screw:

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.
