  • Application of four point contact ball bearing - XZWD

    2019-5-9 · The four-point contact ball bearing is a radial single row angular contact ball. Slewing bearings have raceways designed to handle two-way axial loads. These bearings require minimal space and can withstand both pure axial loads and combined loads. These bearings are used in a variety of industries to provide greater precision and safety.

  • 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 ...
