Deep groove ball bearings are used in a particularly wide variety of applications. Consequently, they are available in many executions and sizes. The standard SKF range comprises the following types:

single row deep groove ball bearings

single row deep groove ball bearings with filling slots

stainless steel single row deep groove ball bearings

double row deep groove ball bearings

single row hybrid deep groove ball bearings, see section "Engineering products

Deep groove ball bearings are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. The inner and outer ring of single row deep groove ball bearings have a deep groove raceway, the bearings are mainly used to carry radial loads and a part of axial loads in two directions. This kind of bearing can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed angular contact ball bearings.   Deep groove ball bearing have various types in structure, beside open type bearings, shield or seals at both side can also be provided.

Deep groove ball bearing is the most commonly used rolling bearing.Its structure is simple, and it can be easy to operate.They are mainly used for standing the radial load. But when the radial play is increasing, they have the performance of angular contact bearing assembly. In that case, they may simultaneously stand the radial loads and the axial loads.In some cases, which are not suitable to using spherical roller thrust bearing and the rotational speed is rather high. They can also be used to stand purely axial loads.Compared with other kind of bearings with the same size, this kind of bearing enjoys smaller coefficient of friction and higher limits speed. But they cannot bear impact. Therefore, they are not suitable to bear heavy load.

　　After installing the deep groove ball bearing in the axis, within the scope of radial play, we can limit the axial position of the axis and the outer cover. Thus they can be used in both directions as axis-position.Moreover, this kind of bearings also has some aligning ability. Being inclined 2’~10’ comparing with outer cover, they can also operate normally. But, it has certain influence to the bearing life.The deep groove ball bearing can be widely used in automobile, tractor, engine bed, electrical machinery, water pump, agricultural machinery and fabrics machine, etc.

Characteristic of deep groove ball bearing:

Explanation:
　　Z represents that one-side of the deep groove ball bearing is mental dust cover, and ZZ represents that both sides are mental dust cover.
　　RS represents that one-side of the deep groove ball bearing is non-touch grommet, and 　　2RS represents that both sides are non-touch grommet.
　　RZ represents that one-side of the deep groove ball bearing is contact grommet, and 2RS represents that both sides are contact grommet
