Deep Groove Ball Bearings

Deep groove ball bearing is the most typical rolling bearings with extensive applications. The raceways in both of the rings are in the arc groove form, which can carry radial load and axial load in double directions. They can be applied in situations where high rotating speed and low noise and low vibration are required.

Adequate lubricating grease shall be filled before hand in the sealed bearings and shielded bearings.

For bearings with filling slot, the number of the steel balls can be increased, leading to higher basic load ratings.

Applications of deep groove ball bearings can be found in automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultures machines and various other special machines.

Deep Groove ball bearings generally used pressed steel cages or brass cages. When the outer diameter is less than (inclusive) 400 mm, they use pressed cage with steel sheet and there is no suffix in the bearings code number. When the outer diameter is greater than 400mm, they use brass cages and there is no suffix in the bearings code number.

Permissible Angular Misalignment

Deep groove ball bearings permit angular misalignment between the inner ring and outer ring. The details are given in terms of radial clearance in the following table:
