Bearings-General bearings-Deep groove ball bearings
Miniature bearings

Deep groove ball bearings are used in a particularly wide variety of applications. They are non-separable, capable of operating at high and very high speeds with low noise and low vibration, and require little attention or maintenance in serve. The price advantage makes deep groove ball bearings the most popular of all rolling bearings. Radial load and axial load in both directions can be accommodated. For shielded or sealed types, greasing is not necessary because of pre-lubrication.

Series of 680 / 690 / 600 / 620 / 630 and R are most commonly used.
