Request Information
HIWIN bearing supports are composed of main body, bearings, cover plate, spacers, oil seals, lock nut, and set screws. Matched with the customer´s axial loading requirement, the bearing support has three configuration types: DF, DFD and DFF.

Product Features:
  • Suitable for heavy load applications, such as ballscrew supports for machine tools.
  • Matched with high accuracy, high stiffness ball screw bearings.
  • HIWIN bearing supports could be assembled with HIWIN ballscrews for a total solution.
