A ball screw needs a proper support at its end to hold it axially while letting it turn with as little friction as possible. The NSK WBK series covers this job in machine tools, machining centers, automation equipment and linear positioning systems where rigidity and accuracy matter. MR Industrial Accessories LLC supplies this series to customers throughout the United States and in several Latin American countries, and can help you match a support to your application.

Reading the code helps you narrow down the right reference. WBK identifies the support family. The two digits that follow tell you the size, which corresponds to the screw diameter the support fits. Suffixes such as 01M or 11M separate mounting or configuration variants. So WBK04-01M and WBK04-11M are both size 04, while WBK06-01M and WBK06-11M are size 06. Every complete part number points to one specific support for one screw diameter.

Typical users are machine tool builders, industrial automation and robotics integrators, measuring and testing equipment makers, and handling system suppliers. In shops and production lines that run ball screws on feed axes, these supports keep the screw aligned and supported, which helps limit vibration and wear.

Selection comes down to three things: the screw diameter, whether the fixing is fixed or floating, and the load and speed conditions of the axis. During mounting, alignment with the linear guide and the motor is critical. Lubrication and effective sealing also play a role in how long the support lasts. Bolt tightening and concentricity should follow the manufacturer's instructions.

WBK series supports can be swapped for equivalent products from other brands when the mounting dimensions and load capacities line up. For a replacement, confirm the part number and dimensions before ordering. If you are unsure, send us the details and we will help you identify a suitable equivalent for your equipment.
