1.The discription of  deep groove ball bearing Â
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

1,A variety of models of deep groove ball bearing are used in a widely field .
2,Simple structure and the use of maintenance are convenience. Â
3,Mainly used to bear radial load, but also bear certain axial load, the radial bearings Clearance increase, angular contact ball bearings with the performance, can withstand higher axial loads. 4,bearing such friction coefficient, limit high-speed, size and scope of the changes varied.
5,it adapts movement temperature from -30°C to +120°C.
6,it don't need to lubricate again in the process, because it taken a dust palliative cover and taken to seal completely a turn the bearings assemble have already stuffed with just the right amount of lubrication fat.
7,it don't need to clean again when it should be heated.
5. Mounting :
The method of mounting rolling bearings strongly affects their accuracy,life,and performance,so their mounting deserves careful attention.It is recommended that the handling procedures for bearing be fully investigated by the design engineers and that standards be established with respect to the following items:
1,Clearing the bearings and related parts.
2,Checking the dimensions and finishing of related parts.
3,Mounting procedures.
4.Inspection after mounting.
5,Supply of lubricants.
