Types of Bearings | Uses & Working Mechanisms Explained

Aug 25, 2020· High speeds. The ball bearing’s small point of contact also means less friction. So there is less resistance to overcome and thus it is easier to achieve high speeds with these types of bearings. Roller Bearings. Roller bearings contain cylindrical rolling elements instead of balls as load carrying elements between the races.

Types of Bearings: How They Work? Parts, Uses [PDF]

Nov 05, 2021· #4 Rolling Contact or Anti-friction bearings It is a well-known fact that a smooth rounded surface will roll over a similar surface more than when it is sliding. This phenomenon employs hard chrome steel balls or rollers to run in special design cages to provide bearings with low friction loss.
