NSK Ball Screw Supports/Pillow Block, 35 mm Shaft Diam., 2900 mm Shaft Length | WBK35DFD-31

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.
