Deep groove ball bearings can be divided into two types of single and double row, in addition can also be divided into sealed and open, which can also be divided into sealed sealed and anti-oil seal.
In addition to these two sub-law, in the deep groove ball bearings, there are a variety of denatured structure, with a dust cover deep groove ball bearings, rubber seals with deep groove ball bearings, with a groove Ball bearings, deep ball bearings with large load capacity, and double row deep groove ball bearings.
Deep groove ball bearings, which are mainly subjected to radial loads, but also can withstand axial load, if only bear radial load, then the contact angle is zero, but if the axial load, the contact angle is not zero The In general, deep groove ball bearing friction coefficient is very small, and the limit speed is very high.
Deep groove ball bearing size range:
Diameter: 10-1320mm
Outside diameter: 30-1600mm
Width Size: 9-300mm
When we use deep groove ball bearings, pay attention to the load can not be too small, otherwise it will slip between the ball and the raceway phenomenon, so that the bearing abrasions, so this should pay special attention to the.
Deep groove ball bearings used for some time, there may be rust phenomenon, the general reasons for the phenomenon are:
(1) the roughness of the metal surface is too large;
(2) the sealing effect of the sealing device is not very good, so that dirt or moisture intrusion;
(3) the bearing for a long time without, or did not carry out maintenance work;
(4) bearing contact with a corrosive chemical medium;
(5) the bearing is not cleaned when cleaned, or not in time for packaging, so exposed to the air;
(6) bearing the storage environment is not good;
(7) bearing coated with anti-rust agent, but the rust agent did not play a role, or quality is not qualified.
