6321M/C3 Bearing Deep groove ball bearings Applications Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc. Ball bearing installation method 1: press-fit: the inner ring of the bearing is tightly matched with the shaft. When the outer ring and the bearing housing hole are loosely fitted, the bearing can be press-fitted on the shaft first, and then the shaft is mounted together with the bearing. Into the bearing housing hole, press-fit on the end face of the bearing inner ring, padded with a soft metal material assembly sleeve (copper or mild steel), the bearing outer ring and the bearing housing hole tightly fit, the inner ring and the shaft are loose When mating, the bearing can be pressed into the bearing housing hole first. At this time, the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly fitted with the shaft and the seat hole, install the inner ring and the outer ring. To simultaneously press the shaft and the seat hole, the structure of the assembly sleeve should be able to simultaneously tighten the end faces of the inner and outer rings of the bearing. The deep groove ball bearing installation method 2: heating fit: by heating the bearing or the bearing seat, using thermal expansion will tighten Cooperate into The matching installation method is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before the hot assembly, the bearing or the detachable bearing ferrule is placed in the fuel tank and heated evenly. 100 ° C, and then removed from the oil as soon as possible to the shaft, in order to prevent the inner ring end face and shoulders from sticking tightly after cooling, the bearing can be axially tightened after cooling. Bearing outer ring and light metal bearing seat tight When mating, the hot-filled method of the heated bearing housing can avoid the surface of the mating surface being scratched. When heating the bearing with the oil tank, there should be a grid at a certain distance from the bottom of the box, or the bearing should be hung with a hook. The bearing should not be placed on the bottom of the box to prevent the sinking of impurities into the bearing or uneven heating. There must be a thermometer in the tank. Strictly control the oil temperature should not exceed 100 °C to prevent tempering effect and reduce the hardness of the ferrule.
