Get Price2020-8-25u2002·u2002Ball bearings' design makes them capable of withstanding axial loads. No heavy loads. Due to having ball-shaped rolling elements, the bearings concentrate all the force onto a few points of contact. This can result in early failure with high loads. High speeds. The ball bearing's small point of contact also means less friction.
Get Price2015-3-25u2002·u2002Ball High bearing stress due to ball-to-ball contact Ball Cage Effect The early forms of ball bearings were full-ball types without ball cages. Friction between balls caused loud noise, made high-speed rotation impossible and shortened the service life. Twenty years later, a Caged Ball design was developed for ball bearings.
