Miniature bearings refer to metric series with an outside diameter of less than 9mm. Inch series deep groove ball bearings with outer diameter less than 10mm. And the bearings MR series are machined components that include an outer ring, inner ring, balls, retainers, shields.

Miniature ball bearings are single row deep groove ball bearings with a bore diameter below 10 mm. Miniature deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and very high speeds and are robust in operation, requiring little maintenance. Single row deep groove ball bearings have deep, uninterrupted raceway grooves. These raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions. Miniature ball bearings are available open or capped (with seals or shields), while the width for these two options are different, the capped miniature bearing is wider than open version, so user needs to pay attention to it when choose the bearing.

Application

The miniature deep groove ball bearings are widely used in motor, fitness equipment, telecommunication equipment, instrument and apparatus, computer, auto motor, precision instrument, machine equipment industries etc.
