The usual device method for small and medium-sized bearings is that the small and medium-sized bearings usually have a small amount of interference; they can be installed with a press at normal temperature; the pressure is best passed through a spherical washer or a steel ball as a preface; to ensure that the force is applied through the axis of the bearing; Prevent lateral tilting. The inner ring and the shaft are in tight cooperation; use different layouts; press the inner ring against the shaft; or press the shaft into the bearing. Then; press the bearing-shaft assembly In the bearing seat. The outer ring and the bearing housing hole tightly cooperate; at this moment, the outer ring should be pressed into the seat hole; then the shaft is loaded into the bearing. The inner ring and the shaft and the outer ring and the seat hole are tightly cooperated; During installation, the inner ring of the bearing is pressed together on the shaft and the seat hole. The inner diameter of the sleeve used should be slightly larger than the inner diameter of the pressurized bearing ring; and the outer diameter should be slightly smaller than the pressurized bearing ring. The outer diameter of the outer diameter; to prevent the sleeve from contacting the shaft or the seat hole.
In the case where the inner ring is pressed together; ensure that the annular pressing end face of the sleeve is flush; the shaft is coaxial with the seat hole and the axial orientation is correct; to prevent one of the end faces of the inner ring from being installed ( There is a gap between the shoulder or the shoulder hole; or damage to the rolling body and the raceway (when the axial difference between the inner ring and the inner ring exceeds the axial clearance of the bearing).
