Various Roller Thrust Bearing Design Types to Suit Any Heavy Applications

Roller Thrust Bearing Design | lakshitahuja.weebly.com

Among various engineering innovations, bearings are one of the revolutionary components that have significantly changed the performance of different machines used in industrial sectors. Rolling bearings are prominent among bearing designs that are largely used to achieve total design economy. Used in automobiles, a thrust roller bearing helps minimize stress and thrust when two mechanical components come into contact with one another when the vehicle is in operation.

These bearings are used in heavy applications to accommodate heavy axial or radial loads at varying speeds. With typical flat ring washers and rollers of spherical, needle or tapered shapes, a roller thrust bearing design is distinctive for performing under shock and impact loads. The line contact on the surface makes the bearing suitable for applications demanding high shock resistance and capacity.

Salient Features of a Thrust Roller Bearing

Roller bearings unlike ball bearings allow easy disassembling and replace of rollers or ring raceways. Rollers, which are spherical or cylindrical shaped support heavy loads. The high axial rigidity of thrust roller bearings make them suitable for several automotive parts like rotating shafts, gear boxes, steering wheels, etc. With some or no radial forces, they handle pure thrust or axial loads.

The easy dismounting and mounting of the bearing components make this bearing unit highly used in the front wheels of the rear-wheel drive vehicles. The inherent feature of this thrust roller bearing design is that the shafts can have the races shrunk fit in the housings to form permanent assemblies, without any risk of damage to the rolling elements.

For different designs and choice, you can refer the roller thrust bearing catalogue available on the manufacturers’ website. It gives complete details of dimensions, sizes and series, with ring washer types and sizes. For greater stability, a roller thrust bearing with cageoffers better maintenance.

Different Types of Roller Thrust Bearing Designs and Uses

As for specific applications, roller thrust bearings of various types are used. The cylindrical roller thrust bearings have barrel-shaped rollers crowned at the ends to manage one or two directional thrust loads. Spherical roller thrust bearings are best suitable for managing misalignment and shaft displacement. They come in different internal clearances, as well as retainer options to accommodate heavy shock loads in either direction. The roller thrust bearing design also includes needle roller bearings to manage radial space constraints.
