Thrust Tapered Roller Bearings

Tapered roller thrust bearings are designed to to carry axial loads with no radial load carrying capacity. They comprise of a shaft washer, a housing washer, and a roller and cage assembly and are separable. These bearings have raceways on the face the washers.By default, AUB tapered roller thrust bearings are equipped with a solid brass cage (suffix: M). Other cage designs are available on request or chosen for specific applications and labelled accordingly on the bearing.

TTC

We make types TTC & TTCS cageless bearings consisting of two tapered thrust races, rollers and an outside retainer. TTC and TTCS types are identical with the exception of the retainer construction.

TTHD

TTHD bearings consist of two thrust races, a set of rollers and a cage. This design can create up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions. The configuration of TTHD bearings creates a benefit called true rolling motion. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation. As a result, true rolling motion reduces heat generation and wear on the races and rollers.

TTHDFL-V-Flat

AUB offer thrust V-flat tapered roller bearings in two types – TTVF (Standard) and TTVS (Self-Aligning) – and combine the outstanding features of tapered thrust and cylindrical roller bearings, offering the highest possible capacity of any thrust bearing of its size.

TTHDFLSA

TTHD bearings consist of two thrust races, a set of rollers and a cage. This design can create up to 40 percent more capacity than cylindrical and spherical bearings with the same envelope dimensions.The configuration of TTHD bearings creates a benefit called true rolling motion. The extensions of the raceways and rollers converge at a common point (the apex) on the axis of rotation. As a result, true rolling motion reduces heat generation and wear on the races and rollers.

TTSP

The TTSPs thrust bearings with two tapered thrust races, rollers, a cage and outside retainer which holds the components together during shipping. Customers use these bearings mostly in the steering pivot positions of automotive and industrial equipment.

Separable designThe shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.
Low frictionThe optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.
Long service lifeDepending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles .
Enhanced operational reliabilityThe surface finish on the contact surfaces on the rollers and raceways supports the formation of a hydrodynamic lubricant film.
High load carrying capacityThe rollers incorporated in AUB tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution and enables the bearings to accommodate heavy axial loads.

Tapered Roller Thrust Bearing -- The angle created between the bearing axis and the line of contact between the raceway and the tapered roller determines the degree of thrust this bearing can accommodate. If this angle is greater than 45°, the bearing is better suited for axial loads. Once the angle between the bearing axis and roller axis reaches 90° the bearing can only sustain axial loads. These bearings require a cage, and sometimes a flange, to retain the roller assembly.
