Angular contact ball bearings have a fundamental feature where the load line of action between the balls and the rolling tracks forms an angle with the geometric bearing axle For this reason the rolling tracks of the inner and outer rings are axially offset from each other allowing endurance of large radial loads in both directions

The Single Row Angular Contact ball bearings have higher axial load capacity than the Single Row Radial ball bearings The bearings can carry axial load in one direction only and are to adjusted against another bearing if axial load is coming from both the directions Each bearing can be located endwise in one direction only
