    2011-5-1 · Roller Bearing vs Ball Bearing A bearing is a device that is used in between two moving or rotating surfaces to facilitate smooth movement and to reduce friction. Bearings have a long history and even before the modern types of bearings came into existence, man used different objects that helped in transportation of large, heavy objects reducing friction.

  • JOURNAL BEARING DESIGN TYPES AND THEIR

    2 天前 · Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape.

  • Types of Bearings - How Bearings Work |

    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 ...
