The bearing hot riveting machine mainly adopts

 **heating and pressure riveting** to permanently fasten components such as bearings, shafts and housings together, preventing loosening and falling off.

It can be simply divided into three steps:

1） Heating Through electric heating or high-frequency heating, the parts to be riveted (shaft ends, rivet columns, sleeves, etc.) are heated to a certain temperature, so that the metal becomes soft and easy to undergo plastic deformation.

2） Pressing & Riveting Pressure is applied to the heated parts by means of dies or pressure heads to produce plastic deformation, forming rivet heads, flanged or expanded structures, so as to firmly lock the bearings with shafts or housings.

3） Cooling & Setting Heating is stopped while pressure is maintained. As the metal cools down, it contracts and hardens, forming a high-strength, non-detachable fastening connection, ensuring that the bearings do not shift or loosen during operation.
