Load type, magnitude and direction of loads are all key in determining the proper type of ball bearing. Specifically, if a ball bearing’s load requirements are only to be able to carry a radial load, then deep groove ball bearings are appropriate. Deep groove ball bearings can carry a thrust load up to 10% of the bearings rated load. Single row angular contact ball bearings can carry radial as well as thrust loads (thrust load in only one direction). However, if the application load requires a thrust in both directions, then a four-point contact ball bearing, or multiple rows of opposing angular contact ball bearings would be options. When only pure thrust loading is involved, there are various types of ball thrust bearings that can be specified.
