The inner and outer rings of tapered roller bearings have tapered raceways, and tapered rollers are arranged between raceways. If conical surface extends, it will eventually reach to an apex point on the bearing axis. This kind of bearing is mainly used to bear radial load mainly and also axial load. The bearing axial load capacity is determined by the contact angle α and the angle of outer raceway.
The larger the α angle is, the larger the axial load capacity. The tapered roller bearing is a separable bearing. The inner ring with roller and cage forms inner assembly and can be installed separately from the outer ring. This kind of bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rows of rollers.
The roller / raceway contact surface of provides the best stress distribution. The special structure of the guided rib and sliding surface of the big end of roller is quite helpful for formation of the lubrication film on the contact surface of the roller end face / the rib. The benefits include increased running reliability and reduced misalignment sensitivity.
According to the actual size requirements, we can provide imperial or metric dimension. In addition, we can optimize the design on the structure according to actual needs. For example: the structure of cage is changed to pin type; the end face of ring is evenly distributed with annular oil groove; the bore is with spiral groove, etc.
Single Row TRB
This bearing can take radial load and one direction axial load.
Double rows tapered roller bearing
Double row tapered roller bearing can bear heavy complex load (radial and axial) and has good rigidity.
Four rows tapered roller bearing
This kind of bearing has compact structure and can bear large radial and axial shock load in a limited space.
