What are the assembly methods of bearings?

Bearing assembly methods are as follows:

1, hammering method

The method of using a hammer to pad the purple copper rod and some relatively soft materials and then hammer should be careful not to make the copper dust and other foreign matter fall into the bearing raceway, and not directly hit the inner and outer rings of the bearing with a hammer or a punching barrel, so as not to affect the matching accuracy of the bearing or cause damage to the bearing.

2, screw press or hydraulic press assembly method

For bearings with large interference tolerances, screw presses or hydraulic presses can be used for assembly. Before pressing, the shaft and bearing should be flattened and coated with a little lubricating oil, the pressing speed should not be too fast, and the pressure should be quickly removed after the bearing is in place to prevent damage to the bearing or shaft.

3, hot loading method

The hot loading method is to heat the bearing in the oil to 80℃-100℃ so that the inner hole of the bearing is enlarged and fitted to the shaft, which can prevent the shaft and bearing from damage. Bearings with dust caps and seals that are filled with grease are not suitable for hot mounting.
