The two basic types of rolling element distinguish the two basic types of rolling bearing: Ball → ball bearing. Roller → roller bearing. Balls and rollers are different in how they make contact with the raceways. Balls make point contact with the ring raceways ( fig. 2 ). With increasing load acting on the bearing, the contact point becomes ...
