Deep groove ball bearings are the most common Rolling bearings. Its structure is simple and easy to use. Used primarily for radial load, but when you increase the radial clearance of bearings, has a certain amount of angular contact ball bearings, can be subjected to combined radial and axial loads. When in high speed and inappropriate use of thrust ball bearings can also be subjected to purely axial loads. Compared with other types of bearing of the same size, the bearings low friction, high speed limit. But not shock resistant and should not be subjected to heavy loads

Types:

– Single row deep groove ball bearings

– Single row deep groove ball bearings with filling slots
