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
