The tapered roller bearing belongs to the separated type bearing, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types based on the number of rows of installed rollers, such as single row, double row, and four row tapered roller bearings. Single row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing is subjected to radial load, an axial force will be generated, so another bearing capable of withstanding opposite axial forces is needed for balance.

1. A single row tapered roller bearing has an outer ring, and its inner ring and a set of tapered rollers are enclosed by a basket shaped cage as an inner ring assembly. The outer ring can be separated from the inner ring component, and any standard model of tapered roller bearing outer or inner ring component should be able to achieve international interchangeability with the same model of outer or inner ring component.

The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The two inner (or outer) rings have similar small end faces and a spacer ring in the middle. The clearance is adjusted by the thickness of the spacer ring, or the pre interference of the double row tapered roller bearing can be adjusted by the thickness of the spacer ring.

3. Four row tapered roller bearings, this type of bearing has the same performance as double row tapered roller bearings, but bears a greater radial load than double row tapered roller bearings, with a slightly lower limit speed. It is mainly used in heavy-duty machinery.

4. Multi sealed double and four row tapered roller bearings, long service life. Personalized and brand new design of bearings, changing the traditional design method of fully sealed bearings, adopting a new sealing structure combining sealing and dust prevention to improve sealing effectiveness and enhance sealing performance. Compared with open structure bearings, the lifespan of multi sealed double and four row tapered roller bearings is increased by 20% to 40%; Reduce lubricant consumption by 80%.
