The metric size tapered roller bearing is a very widely used product. Its market share and usage are second only to deep groove ball bearings, ranking second, in construction machinery, mining machinery, transportation machinery and vehicles. In, there were applications. The load capacity is large, the rigidity is good, and the axial and radial loads can be withstood at the same time. The speed performance is also very good. It is because of so many advantages that the metric size tapered roller bearing can be applied in so many fields.

In normal operation, the inner raceway, outer raceway and roller of the metric tapered roller bearing are subjected to load, while the cage acts as a roller to separate and maintain stability, the inner ring, the roller and The cages are usually assembled together.

The inner ring of a metric-sized tapered roller bearing has two ribs, each having a different function, and the small rib is integrated with the cage to integrate the roller and the inner ring. The large rib can withstand the axial component of the tapered roller. The conical structure of the roller not only ensures the load on the contact surface, but also pushes the roller towards the large rib of the raceway. The tapered roller rolls on the raceway and also rolls along the large rib.

The load is transmitted through the rolling element through a ferrule to the other ferrule, which is inside the bearing of the metric size tapered roller bearing. The amount of load that each rolling element is subjected to depends on the geometry inside the bearing and the type of load acting on the bearing.
