Introduction to the installation of small bearings

General installation of small and medium-sized bearings: small bearings generally small amount of interference, you can press at room temperature installation, the best pressure through the spherical washers or a steel ball as a medium to ensure that the force through the bearing axis , To avoid side skew. The inner ring and the shaft are in tight fit. With different structural tools, the inner ring can be pressed on the shaft or the shaft can be pressed into the bearing. Then press the bearing-shaft assembly into the housing. Outer ring and bearing housing tight fit, this time should be pressed into the outer ring seat hole, and then the shaft into the bearing. The inner ring and the shaft and the outer ring and the seat hole are tight fit, the inner and outer rings of the bearing are pressed on the shaft and the seat hole at the same time during assembly. The inner diameter of the sleeve to be used should be slightly larger than the inner diameter of the bearing sleeve, and its outer diameter should be slightly smaller than the outer diameter of the bearing sleeve to prevent the sleeve from interfering with the shaft or seat hole. In the same time the inner and outer rings into the case, should ensure that the inner and outer sleeve annular pressure surface flush with the axis coaxial with the seat hole and the axial position is correct, in order to avoid the inner and outer ring end can not be fitted to the end (with shoulder Or seat block retaining gap between the shoulder), or damage to the rolling body and raceway (when the inner and outer rings along the axial position difference exceeds the bearing axial clearance).
