NSK Standard Ball Screw W3205SA-2Z-C5Z5 Ball Screw for Automated Equipment

The NSK W3205SA-2Z-C5Z5 SA type tubular circulating ball screw has a diameter of 32 mm, a lead of 5 mm, and a total length of approximately 760 mm. It features a right-hand thread design, adopts a C5 precision grade, and possesses high precision, low backlash, and high-efficiency transmission characteristics.

The NSK SA type ball screw is a precision-ground standard ball screw. Its core feature is that the shaft end has been precision-machined, allowing direct installation with NSK standard support units. This eliminates the need for secondary shaft end machining by the user, significantly shortening the assembly cycle.

Design Features and Performance Advantages of the W3205SA-2Z-C5Z5 Backlash-Free Ball Screw

High Precision and High Rigidity: C5 precision grade, suitable for high-precision positioning requirements, and capable of achieving zero backlash.

High Efficiency and Long Life: Utilizing rolling friction and optimized groove design, transmission efficiency reaches over 90%. Meanwhile, the choice of materials ensures excellent durability.

Finished Shaft Ends: The journals at both ends of the ball screw are pre-machined to NSK standards, allowing direct installation of NSK matching support units (such as the WBK type), saving time and effort.

Pipe Circulation: Steel balls smoothly flow back through a tube inserted into the nut, resulting in low operating noise and a wide range of applications.
