What is the difference between a roller bearing and a ball bearing? | Nippon Bearing

22/2/2018· A roller bearing is a cylindrical unit that is used to provide low-friction movement for a bushing or bearing block. A ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail. For ball bearings (assuming a perfectly

Radial and Axial Load Rating Information for S Bearings

If long life is required, it is preferable to limit the actual load to between 6% and 12% of a bearing’s dynamic load rating. Heavier loads can be tolerated but life will be shortened. AISI440C/KS440 stainless steel bearings will support approximately 80% - 85% of the load figures for chrome steel bearings.
