Roller Type Supporting Roller Features

high radial load, can withstand combined load, long life

  • High radial load: The thicker wall thickness outer ring can not only bear high radial load, but also reduce deformation and bending stress when working as a roller.

  • Can withstand axial load: Cylindrical roller bolt shaft rollers with baffle type can withstand axial load that may result from off-loading or inclined operation.

  • Long service life: The convex design of the outer ring surface can be greatly improved to cope with the possible inclination of the outer ring with respect to the working track surface, or where the edge stress needs to be minimized.
