Usually, Tapered Roller Bearings are detachable type, which the cone inner ring component with roller and retainer can installe separately from the cone outer ring. Tapered Roller Bearings are cone-shaped inner and outer ring raceway and tapered roller arranged between the two. The projection line of all the cones’ surface meet together at the same point in the bearing axis line. This design to make tapered roller bearings particularly suitable for composite bearing (radial and axial) load.
Single row Tapered Roller Bearings is the commonest in usage of Tapered Roller Bearings. However, the small size of the double row Tapered Roller Bearings are used in the front wheel of the car wheel in the recent years. Four-row tapered roller bearings are used in large-scale cold and hot rolling of heavy machinery, etc.
Tapered Roller Bearings are widely used in automotive, mill, mining, metallurgy, plastics, machinery and other industries.
