Bearing Manufacturer 62209CM NTN KOYO Brand Bearing Deep Groove Ball Bearing

Working principle:

Deep groove ball bearings mainly bear radial load, but also can bear radial load and axial load. When it is only under radial load, the contact Angle is zero. When the deep

groove ball bearing has a larger radial clearance, it has the performance of angular contact bearing and can withstand larger axial load. The friction coefficient of deep groove ball bearing is very small and the limit speed is very high.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. Deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.

The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a group of steel balls and a group of cages. There are two types of deep groove ball bearing, single row and double row, deep groove ball structure is also divided into sealed and open two kinds of structure, open refers to the bearing without sealing structure, sealing type deep groove ball is divided into dust seal and oil seal. The dust proof sealing cover is made of steel plate stamping, which only prevents dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease spillover in the bearing.
