NSK W3207SA-5Z-C5Z8 high-precision ball screw 8mm small lead ball screw

The NSK W3207SA-5Z-C5Z8 is an SA-type small-lead, shaft-end finished ball screw with a nominal diameter of 32 mm, a lead of 8 mm, and an accuracy class of C5.

The SA-type W3207SA-5Z-C5Z8 ball screw uses a tube-circulation structure, meaning the balls circulate through a return tube inserted into the nut body. Tube-circulation types are commonly used in medium to large-sized ball screws, offering smooth operation and uniform force distribution, making them suitable for high-load working environments.

The NSK W3207SA-5Z-C5Z8 ball screw features the following characteristics:

High precision: C5 grade precision, small lead error, high positioning and repeatability accuracy;
High transmission efficiency: The rolling friction structure of the balls achieves a transmission efficiency of over 90%, resulting in smooth operation and low energy consumption;
High rigidity and high load capacity: The 32 mm large diameter design can withstand large axial loads while maintaining good motion stability;
Low backlash: The offset preload design effectively reduces axial backlash, improving motion control accuracy and response speed;

Main applications of the W3207SA-5Z-C5Z8 ball screw include:

CNC machining centers

CNC lathes

Precision grinding machines

Semiconductor equipment

Automated assembly lines

Seventh axis of industrial robots

Optical inspection platforms

Medical equipment
