Type
A single
Single row tapered roller bearings can withstand combined radial and axial loads. However, if the application has bidirectional axial loads, two single-row tapered roller bearings can be used together in back-to-back or face to face mounting mode.
Double row
Double row tapered roller bearings are specially designed to withstand radial and bidirectional axial loads.
Four row
In addition to the standard functions of double row tapered roller bearings, four row tapered roller bearings can also withstand heavier radial and impact loads. Ideal for very high load applications.

According to customer requirements
Tapered roller bearings are used in agriculture, automobiles, heavy trucks, cement, aggregates, coal, oil and gas, construction, gear drives, machine tools, mining, paper, metals, railways and wind energy. It can improve the performance of demanding applications.
When selecting a bearing for a specific application, many factors need to be considered:
Type of load, such as radial, axial or a combination of radial and axial and the magnitude of these loads
Running speed，Required operating accuracy，Available space，dislocation，Noise level.
