Different sizes and outer contours for use in standard U-profiles and in precision profiles. Fitted with rolling bearings or plastic plain bearings depending on environment, application and load.
Advantages of combined rollers
- low design and assembly costs
- simple design of the mating structure, thereby improving manufacturing costs
- absorption of high radial and axial loads
- improved combined roller design for high static and dynamic loads
- the outer contour geometry ensures good load introduction
- long service life thanks to robust component design
