Deep groove ball bearing structure is simple, easy to achieve compared with other types of manufacturing high precision, so easily into a series of mass production, lower manufacturing costs, the use of extremely common. In addition to the basic type of deep groove ball bearings,using thermal heating bearing installation method, you can avoid with the surface by abrasion. When the tank is heated by the bearings, should be at a certain distance from the bottom grid network, or hung with a hook bearing, the super-precision bearing can not be put on the bottom to prevent the heavy impurities into the bearing, or uneven heating, the tank must have a thermometer, strictly control the oil temperature must not exceed 100 ℃, in order to prevent tempering effect, reducing the hardness of the ferrule.
