The Single Row radial ball bearing has a single row of balls and can take pure radial, loads within its load capacity. It is widely used because it can operate at very high speeds due to its low torque and is cost-effective at an economical price.
As there is high degree of conformity between balls and raceways, the self-aligning capability of deep groove ball bearings is less, and therefore require well aligned bearing mountings. These bearings can be located endwise 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.
These bearings, when mounted in a duplex arrangement, provide axial and/or radial rigidity in applications where control of shaft displacement is essential.
