Key Analysis of Force Application When Installing and Removing Bearings

.1) The combined force of the force can pass through the axis of the bearing; this requires that the point of application is uniformly symmetrical and stable; the force is applied through the spherical surface or parallel to the axis.
.2) The size of the force should be smooth and uniform; it should not be impacted; this requires the use of oil pressure or something that can apply a smooth tension or pressure; the real has to use hammering; also through the copper sleeve and other soft Do not use the metal to cushion; the tapping force can be light. The best use of copper rods or copper hammers for hammering.
.3) Prevent the force from being applied through the tumbling body; this requires the force applied through the inner ring when the inner ring (shaft ring) is assembled and disassembled; when the outer ring is assembled and detached, the force is applied through the outer ring.
.4) The drag force should be continued to the extent it should be; for example, when the bearing is mounted, the force should be stopped when the bearing is just in the correct orientation; ensure that the end face of the ferrule (gasket) abuts against the shoulder hole or the shoulder end face of the shaft; Can't be squeezed too tightly;
