Tapered roller bearings: high wear resistance and high load-bearing capacity
2026-07-02
Tapered roller bearings, based on the number of rows of rollers, are divided into single-row, double-row, four-row and other design types. Single row tapered roller bearings are capable of supporting radial load and axial load in the same direction. When a bearing perceives a radial load, an axial component arises, to balance which another bearing is required that can absorb an axial force in the opposite direction.
The most common among tapered roller bearings are single-row tapered roller bearings; The front wheels of passenger cars use smaller double row tapered roller bearings, while four row tapered roller bearings are typically used in large machines such as large cold and hot rolling mills. Below we will talk about the types and dimensions of tapered roller bearings.
Tapered roller bearings - classification
In daily life, the most common tapered roller bearings can be divided into: single row tapered roller bearings, double row tapered roller bearings, four row tapered roller bearings. In a single-row tapered roller bearing, the design of the outer ring can be separated from the inner assembly; According to the ISO standard for overall dimensions of tapered roller bearings, the outer ring or inner assembly of any standard size of tapered roller bearing must be internationally interchangeable with an outer ring or inner assembly of the same size. Generally, the raceway cone angle of the outer ring of a single row tapered roller bearing is in the range of 10° to 19°; it is able to simultaneously perceive the combined action of axial and radial loads. The greater the cone angle of a tapered roller bearing, the greater its ability to support axial load.
