25x62x17 Bearing

 These types of bearings are designed to work with various thrust loads and radial loads. The biggest difference is that the weight of a particular bearing is much stronger than the others.There are several types of bearings. Designed for specific applications and designed to withstand specific types of loads, thrusts or radial.The most popular types of bearings are ball bearings, Tapered Roller Bearings, Ball Thrust Bearings, and Roller Thrust Bearings etc.

In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly. But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the bearing.
