Structurally, each ring of deep groove ball bearing has a continuous groove raceway, the cross section of which is about one third of the equatorial circumference of the ball. Deep groove ball bearings are mainly used for bearing radial load, but can also bear some axial load.

When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the alternating axial load from two directions. Compared with other types of bearings of the same size, this type of bearing has advantages of low friction coefficient, high limit speed and high precision, so it is a preferred type of bearings for users.

Main application of deep groove ball bearings: Automobile, tractor, machine tool, electric motor, water pump, agricultural machinery, textile machinery, etc.
