Tapered roller bearings are separate bearings. The inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an axial component force will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.

The tapered roller bearing contains sections of a cone as a load-carrying element. These rollers fit between the two races that are also sections of a hollow cone. If the races and the axes of rollers were extended, they would all meet at a common point.

Tapered roller bearings are designed to handle higher axial loads besides radial loads. The larger the half-angle of this common cone, the more axial load it can sustain. Thus they work as thrust bearings as well as radial load bearings.

The basic dimensions of UQG tapered roller bearings are listed in the dimensional data sheet

Single-row Tapered Roller Bearings: Most basic and widely used tapered bearing. Usually fitted as one of an opposing pair. During equipment assembly, can be set to the required clearance (end play) or preload condition to optimize performance. 

Single-row tapered roller bearings:

Inner diameter size range: 20mm~1270mm

Outer diameter range: 40mm~1465mm

Width size range: 15mm~240mm

Double-row Bearings: Two-row tapered bearing arrangements offer increased load capacity over single types.

Double-row tapered roller bearings:

Inner diameter size range: 38mm~1560mm

Outer diameter range: 70mm~1800mm

Width size range: 50mm~460mm

Four-row Bearings: Combine the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings into assemblies of maximum load rating in a minimal space.

Four-row tapered roller bearings:

Inner diameter size range: 130mm~1600mm

Outer diameter size range: 200mm~2000mm

Width size range: 150mm~1150mm
