NSK SA Ball Screw W2002SA-4P-C5Z5 Small CNC Milling Machine Ball Screw

The W2002SA-4P-C5Z5 is an NSK ball screw with a 20mm diameter and 5mm lead, featuring a precision-ground SA-grade pre-finished shaft end. The shaft end is pre-machined at the factory, requiring no further processing, and can be directly installed with a standard support unit.

The W2002SA-4P-C5Z5 ball screw utilizes a single-nut interference preload to achieve zero axial backlash. With a C5 precision rating, it features a compact structure, accurate positioning, smooth operation, and moderate rigidity, making it suitable for small to medium-sized precision platforms, engraving machines, automated equipment, and testing instruments—situations requiring backlash-free precision transmission in both forward and reverse rotation.

Key Features of W2002SA-4P-C5Z5 Ball Screw: High Precision and High Rigidity: C5 grade precision ensures excellent axial clearance and positioning accuracy.

SA Series Advantages: Designed specifically for industrial machinery, offering reliable transmission efficiency and a long service life.

Preload: Utilizes precision preload technology to reduce errors caused by thermal expansion and enhance positioning rigidity.
