W2805SA-4Z-C5Z6 Z-preloaded Ball Screw SA type Tube Circulating Ball Screw

The NSK W2805SA-4Z-C5Z6 is a small-lead, 50mm lead ball screw with a finished shaft end. It is of type SA, uses offset preload (0 axial clearance), has a precision class of C5, and can achieve precise linear motion. The screw is approximately 699mm long and is suitable for applications requiring precise positioning, such as automated equipment and machine tools.

The main features of the NSK W2805SA-4Z-C5Z6 ball screw are as follows:

Core Positioning: An NSK SA-type end-finished ball screw for machine tools, specifically designed for CNC machine tools and precision automation equipment.

High Precision and Zero Backlash: The W2805SA-4Z-C5Z6 ball screw has a precision grade of C5. The "Z" in the model number indicates offset preload, achieving zero axial backlash, effectively eliminating reverse stroke and ensuring accurate and stable positioning.

Long Life and Easy Installation: The screw shaft undergoes precision heat treatment, achieving a surface hardness of HRC 60-65, making it wear-resistant, durable, and with excellent precision retention. The W2503SA-4P-C5Z10 end-finished ball screw features a standardized design, with the shaft end machined pre-machined at the factory, allowing direct compatibility with NSK standard support units, significantly shortening the assembly cycle.

Typical applications of SA type c5 precision ball screws:

Precision machining centers, CNC milling machines/lathes

Automated production lines, precision positioning platforms

Semiconductor equipment, testing instruments

Medical equipment, optical instruments
