As different row configurations for rollers are required, tapered roller bearings can also be divided to double row tapered roller bearings and four row tapered roller bearings. These bearings have the advantage of combined load capacity in both radial and axial environments. Compared to other bearings of the same size, these tapered roller bearings have a relatively longer working life.

Tapered roller bearings are widely used in heavy-duty gear drives, mining,gear reduction units, plastics machinery and a host of other industries.

This has a one-piece (double) outer ring and two single inner rings. It is usually supplied complete with an inner-ring spacer as a pre-set assembly. This configuration gives a wide effective bearing spread and is frequently chosen for applications where overturning moments are a significant load component. TDO bearings can be used in fixed (locating) positions or allowed to float in the housing bore, for example, to compensate for shaft expansion. TDO CD outer rings also are available in most sizes. These outer rings have holes in the O.D. that permit the use of pins to prevent outer ring rotation in the housing.MONTON M919048/M919010D is widely used in automotive,rolling mill,mining, metallurgy,plastics machinery and other industries.
