Tapered roller thrust bearings

Single-row thrust tapered roller bearing is a radial thrust rolling bearing whose rolling elements are tapered rollers. This kind of bearing can bear radial and axial loads in one direction. An axial force component will be generated when the bearing is subjected to radial load. Therefore, single-row thrust tapered roller bearings are often used in pairs when another bearing that can withstand axial force in the opposite direction is required for balance.

Characteristics of Single-row thrust tapered rollers bearings

It can bear radial and large unidirectional axial loads and pure axial loads.

The inner and outer circles can be separated, the gap can be adjusted, and the limit speed is low.

Usually used in pairs and installed symmetrically, they can limit the one-way axial displacement of the bearing and meet the requirements for one-way axial positioning.

These characteristics make single-row thrust tapered roller bearings widely used in heavy machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors, and other machinery.

FV produces single direction taper roller thrust bearings in two designs which differ in the execution of the washers.

Design (1) have shaft and housing washers which have the same dimensions. These washers both have a tapered raceway and one retaining flange. Bearings of this design are to be preferred where very heavy axial loads occur as, for example, in the swivels of drilling rigs or in crane hooks. The bearings have a cage which is centred on both washers.

Design (2) have a shaft washer with tapered raceway and retaining flange whereas the housing washer is plane (flat). Therefore, bearings of this design are able to accept minor eccentricities of the shaft with respect to the housing bore without any detrimental influence on bearing performance. With the exception of a few sizes which have a full complement of rollers, the bearings are fitted with a roller centred cage. 

The difference between single-row thrust tapered roller bearings and double-row thrust tapered roller bearings

Different structures: Single-row tapered roller bearings have an outer ring, an inner ring, and a cage assembly, while double-row tapered roller bearings have two outer rings (or inner rings) and two cage assemblies.

The ability to bear loads differs: single-row tapered roller bearings can only bear one-way axial loads, while double-row tapered roller bearings can bear two-way axial loads.

Different use applications: Single-row tapered roller bearings are usually used in heavy machinery, such as construction and metallurgical machinery. At the same time, double-row tapered roller bearings are more commonly used in precision machinery and aerospace equipment.
