Deep Groove Ball Bearings
Deep groove ball bearings are one kind of radial bearings widely used.They are simple in structure non-separable cheap in its price.In addition they require little maintenance in service as wll as are capable to be operated at high speeds.
Both the inner ring and outer ring of deep groove ball bearings have a deep groove raceway in addition the good sealing quality between raceway and ball can make bearings carry radial loads as well as certain axial loads.After the radial clearance is increased properly axial load carrying capacity will be improved accordingly.That’s the reason why it can replace high speed angular contact ball bearings in some cases.
As to cages, pressed steel ones are the most common.For big deep groove ball bearings, machined brass cages are used.Machined cages are also used for high speed applications
Deep groove ball bearings are widely used in automotives, tractors, machine tools,generators, water-pumps, agriculture machinery, textile machinery, etc.
