The inner and outer rings of tapered roller bearings have tapered raceways, and the tapered rollers are arranged between the raceways. If the tapered surface extends, it will eventually reach the top point on the bearing axis. This type of bearing is mainly used to bear radial load, but also used to bear axial load. The axial load capacity of the bearing is determined by the contact angle α and the angle of the outer raceway.

The larger the α angle is, the larger the axial load capacity is. Tapered roller bearings are separable bearings. The inner ring with rollers and cage constitutes the internal assembly and can be mounted separately from the outer ring. These bearings can be divided into single row, double row and four row tapered roller bearings according to the number of roller rows.

The roller/raceway contact surface provides optimum stress distribution. The special structure of the guide baffle and sliding surface of the large end of the roller facilitates the formation of a lubricating film on the roller end/baffle contact surface. Benefits include increased operational reliability and reduced susceptibility to misalignment.

Depending on the actual dimensional requirements, we can provide imperial or metric dimensions. In addition, we can optimize the design of the structure to meet actual needs. For example, the cage structure is changed to pin type; the ring end face is evenly distributed with annular oil grooves; the holes have spiral grooves, etc.
