  • Four-point contact ball bearings | SKF

    Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported . The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two ...

    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.

    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 ...
