NSK Ball Screw Assembly, 20mm Shaft Diam.

The NSK Ball screw support units designed for use in precision machinery such as CNC machines, automation systems, and other high-speed, high-load applications. Serving as fixed-side support units, they ensure accurate axial positioning and smooth rotational motion. They feature preloaded angular contact ball bearings for high rigidity and are pre-packed with grease for long-term operation. The housing style includes a round flanged design depending on the model, making them ideal for high-speed, high-load, and high-accuracy environments.

High rigidity and load capacity
Clean versions use low dust grease and low torque bearings
High-strength steel with black oxide coating for corrosion resistance
Side mounting with set screw flats
Simple support side units use sealed deep groove ball bearings
