When assembling a bearing, the most basic requirement is to make the added axial force act directly on the end face of the ring of the installed bearing (when installed on a shaft, the added axial force must act directly on the inner ring. When it is on the hole, the added force should act directly on the outer ring). Try not to affect the rolling elements. Assembly methods include hammering, press assembly, hot assembly, freezing assembly, etc.

1. Hammering method

Use a hammer to pad the copper rod and some softer materials before hammering. Be careful not to let foreign matter such as copper dust fall into the bearing raceway. Do not directly use a hammer or punch to directly hit the inner and outer rings of the bearing to avoid affecting the bearing's performance. Fitting accuracy may cause bearing damage.

2. Screw press or hydraulic press assembly method

For bearings with large interference tolerance, screw press or hydraulic press can be used for assembly. Before pressing, the shaft and bearing should be laid flat and a little lubricating oil should be applied. The pressing speed should not be too fast. After the bearing is in place, the pressure should be removed quickly to prevent damage to the bearing or shaft.

3. Hot loading method

The hot-fitting method is to heat the bearing in oil to 80℃-100℃, expand the inner hole of the bearing, and then put it on the shaft to prevent the shaft and bearing from being damaged. The hot-fitting method is not suitable for bearings with dust covers and seals that are already filled with grease.
