Four-Point Contact Ball Bearings: inform yourself & order

Four-point contact ball bearings Due to the large contact angle on both sides, the bearings can support alternating, pure axial or predominantly axial loads. Four point contact bearings are similar in their structure to double row angular contact ball bearings, but are considerably narrower in an axial direction due to only one raceway groove.
