Deep-groove Ball Bearings

Deep groove bearings (single-row deep groove ball bearings) are the most typical forms of ball bearings (rolling bearings) and are the most widely used. They consist of a combination of raceway rings (inner and outer rings), balls, and a cage that supports the balls.

Basically, they are mainly designed to support radial loads (perpendicular to the axis), but they can also support axial loads in both directions.

It has a low coefficient of friction and is suitable for applications that require stable rotation.

The groove of the raceway ring is a circular arc slightly larger than the radius of the ball, so the ball and raceway ring are in point contact. Compared to plain bearings, the use of balls lowers the resistance to rotation, making them suitable for applications that require stable rotation.

The structure of the bearings

We mainly use plastic as a bearing material. Plastic bearings have various features that are different from metal bearings, such as they can be used without lubrication or oiling, and they do not rust or corrode when exposed to water or chemicals.

The features of the bearings

Plastic bearings are used in special environments where metal bearings cannot be used. However, no single plastic material is suitable for all special environments, so we recommend different materials depending on the environment in which they will be used. In addition, since we manufacture by cutting, we can manufacture any shape.

If you have any problems with bearings, etc., we will be happy to visit you, so please feel free to contact us.
