The difference between double row angular bearing and double row deep groove ball bearing

The design of double row deep groove ball bearing is basically the same as that of single row deep groove ball bearings. Deep groove ball-shaped raceway has an excellent adhesion between the raceway and the steel ball. In addition to the radial load, the double row deep groove ball bearings can withstand axial loads acting in both directions.

double row deep groove ball bearing have a radial load capacity of 1.62 times higher than that of single row deep groove ball bearings. They are suitable for bearing arrangements with insufficient load capacity of a single row deep groove ball bearing. Double row deep groove ball bearings are not only subjected to radial load. In addition, it can withstand axial loads acting in both directions.

The difference between double row angular bearings and double row deep groove ball bearing:
1. Angular contact ball bearings can withstand large radial forces and large axial forces. Deep groove ball bearings can withstand large radial forces and small axial forces;
2. The contact angles of the two are different. The original contact angle of the deep groove ball bearing is 0°, the contact angle of the angular contact is greater than 0°, generally 15°, 25°, 40°, and greater than 45° is the thrust angular contact bearing;

3. The two bearings are mainly different in the size and direction of the load:
double row deep groove ball bearing have a small bearing capacity and are mainly subjected to radial loads and can also withstand certain axial loads. The friction coefficient is small and the limit rotation speed is high;
Angular contact bearings have increased bearing capacity, can withstand radial and axial loads, and can withstand pure axial loads (can only withstand axial loads in one direction, generally used in pairs) with high limit speeds.
