NSK W3211FA-1P-C5Z25 Flange Nut Ball Screw External Circulation Ball Screw

The NSK W3211FA-1P-C5Z25 is a FA series large-lead, shaft-end finished ball screw with a nominal diameter of 32 mm, a lead of 25 mm, and an accuracy class of C5.

The FA type W3211FA-1P-C5Z25 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, featuring smooth operation and uniform force distribution, making them suitable for high-load working environments.

Features of NSK W3211FA-1P-C5Z25 Ball Screw:

Large Lead and High Speed: With a lead of 25mm, it significantly reduces positioning time, making it ideal for automation scenarios where efficiency is paramount.

High-Precision Positioning Capability: With a C5 accuracy class, it achieves high-precision and repeatable positioning, smooth operation, and minimal transmission error.

Zero Backlash and High Rigidity: Utilizing a "P" (interference ball preload) method, it achieves 0mm axial backlash, eliminating idle travel during reversal, resulting in stronger system rigidity and ensuring machining accuracy.

Typical applications of the W3211FA-1P-C5Z25 ball screw:

CNC machine tools and industrial robots: Meets the requirements for high dynamic response and high-precision feed.

Automated assembly lines: Its high speed and high precision are core performance requirements for high-speed assembly lines in industries such as electronics manufacturing.

Aerospace and automotive industries: Suitable for applications with extreme requirements for component reliability and durability.

Semiconductor and FPD manufacturing equipment: Meets the high requirements for cleanliness and precision in these special environments.
