1. Introduction to Deep Groove Ball Bearings:
Deep groove ball bearings are among the most widely used types of rolling bearings. They feature raceway grooves on both the inner and outer rings that have a slightly larger radius than the balls themselves. These bearings can handle both radial and axial loads in either direction. Due to their low torque, they are ideal for high-speed applications where minimal power loss is required.
In addition to open bearings, these bearings often come with steel shields or rubber seals on one or both sides, pre-lubricated with grease. Snap rings may also be used on the periphery. The most common cage material is pressed steel.
