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.

Deep groove ball bearing type

In addition to the open type, these bearings also include sealed grease-sealed bearings and bearings with snap rings on the outer ring. Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings, single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without a sealed structure. The sealed deep groove ball is divided into dust-proof and oil-proof. seal. The dust-proof seal cover material is stamped with steel plate, which only serves to prevent dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.
