Deep groove ball bearings are the most common type of rolling bearings. The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of retaining structures. There are two types of deep groove ball bearings: single row and double row. The type code for single row deep groove ball bearings is 6, and the type code for double row deep groove ball bearings is 4. Its structure is simple and easy to use, making it the most commonly produced and widely used type of bearing.

working principle:

Deep groove ball bearings mainly bear radial loads, and can also bear both radial and axial loads simultaneously. When it only bears radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small and the maximum speed is also high.
