Bearing Component：
It consists of an outer ring, an inner ring, a set of steel balls and a set of cages.
It mainly bears pure radial loads, but also can bear joint loads. When it is subjected to pure radial load, its contact Angle is zero. When it has a larger radial game, that is, it has angular contact bearing performance, which can withstand a larger axial load.
Deep groove ball bearing has small friction coefficient and high limit speed, so it has more advantages than thrust bearing when axial load is rotating at high speed. But because its aligning performance is limited, the concentricity of bearing installation should be high, otherwise it will affect the balance of its operation, increase the bearing stress, and thus shorten the working life.
Rubber Sealed Bearings：
Advantages: To prevent any foreign intrusion,super dust effect.
Disadvantages: The price is relatively high,the general speed.
Metal Sealed Bearings：
Advantages: High speed,has a good dust effect.
Disadvantages: Can not prevent the intrusion of liquid debris.
Open Sealed Bearings：
Advantages:High speed,idling effect .
Disadvantages: Dust effect is poor,easy into the dust,impurities and so on.
Bearing Characteristics：
Deep groove ball bearing simple structure, compared with other easy to achieve high precision, so can be mass production. In addition to the conventional models, it also has a variety of structural variations, such as deep groove ball bearing with dust cover, deep groove ball bearing with rubber ring and deep groove ball bearing with a stop groove and so on.
Application：
6018 bearing is mainly used in construction machinery, machine tool, automobile, metallurgy, mining, petroleum, machinery, electric power, railway and other industries.
