What is the difference between a roller bearing and a ball

Feb 22, 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.

Roller bearings VS Ball bearings for Crank bearings - Tech

Dec 04, 2020· Simple answer is ball bearings are decent at both radial loads and thrust loads. Roller bearings are really good at radial loads but are horrible for thrust loads. Replacing the roller bearing with a ball bearing would likely require a small ball type bearing which would probably be better with thrust loads but much worse in radial loads.
