Structure:Deep groove ball bearings are composed 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 divided into two types: sealed and open. The open type means that the bearing does not have 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.Characteristic:Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear the combined radial and axial load. When the speed is high and thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and dimensions of deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not resistant to impact and is not suitable for heavy loads.Use: Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yos, etc.
