Long Life Ceramic Bearings Detail:
Deep Groove Ball Bearings
are easy to install and can be deployed in a variety of configurations. They are the most common form of rolling bearings and are used in many types of applications; particularly those where high speeds and low power loss are required. Deep groove ball bearings can handle not only radial forces, but also moderate axial loads in both directions.
