1. Each ring of the deep groove ball bearing in structure has a continuous groove raceway with a cross section of about one third of the ball circumference. It is mainly used to bear radial loads and can also bear certain axial loads.

2. When the radial clearance of the bearing increases, it has the characteristics of an angular contact ball bearing and can withstand the axial load alternating in two directions.

3. Low friction and high speed.

4. Simple structure, low manufacturing cost, and easy to achieve high manufacturing accuracy.
5. Generally, stamped wave-shaped cages are used, and bearings with an inner diameter greater than 200mm or high-speed running adopt car-made solid cages.

There are more than 60 variant structures of deep groove ball bearings.
