  • » Four-point contact ball bearings – two in one

    2015-6-25 · A four-point contact ball bearing can accommodate axial loads in both directions, in combination with radial loads up to a certain level, and provides a very tight axial shaft position tolerance.The bearing also saves space, because it can be seen as the combination of two single row angular contact ball bearings into one.

  • What is the functions and features of four point

    2021-6-4 · four point contact bearing is a separable bearing, which can also be said to be a set of angular contact ball bearings that can bear bidirectional axial load. The inner and outer ring raceways are peach-shaped cross-sections. When there is no load or pure radial load, the steel ball and the ring appear as four-point contact, which is the origin of this name.

  • four point contact ball bearing application

    2018-10-29 · The four point contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that acts to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support combined ...

  • 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 ...
