Product Description
638 ZrO2 Ceramic Deep Groove Ball Bearings Low Noise For Automotive
Deep Groove Ball Bearing Detail:
Deep Groove Ball Bearings 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. They are easy to install and can be deployed in a variety of configurations.
