deep groove ball bearings are one kind of radial bearings widely used. they are simple in structure, non-separable and cheap in price.in addition, they require little maintenance in service, and they are capable to be operated at high speed.
Both the inner and outer ring of single row deep groove balll bearings have a deep groove raceway, and they are with good sealing quality between raceway and ball.This enable them to carry radial loads as well as certain axial loads.After the radial clearance is increased, the axial load carrying capacity will be improved. This is the reason why they can replace high speed angular contact ball bearings in some cases.
deep groove ball bearings have various types of structure. sealed bearings deep groove ball bearings with a snap ring groove low-noise bearings .
