Four-point contact ball bearings are radial single-row angular contact ball bearings with raceways designed to support axial loads acting in both directions. Compared with double-row angular contact ball bearings, the axial space occupied by these bearings is significantly reduced. The contact Angle of the four-point contact ball bearing is 35 "or 45". The inner picture is to split the inner ring. This allows a larger number of steel balls to be loaded into the bearing, thus giving the bearing a higher load bearing capacity. The bearing is a separate design, that is, the foreign parts of the strip ball and cage assembly can be installed with two inner rings and half rings respectively, and there is an outer picture to split the outer picture, and the inner ring is a whole structure.
