Roller Thrust Bearing

Roller bearings are distinguished by their barrel-shaped rolling elements, which are good enough in accommodating axial loads and pure thrust. With the design variants, you can have them suitable for several applications, which demand managing one-directional or two-directional acting loads, either axial or radial loads or a combination of both. Roller thrust bearings are made of high-precision components, which permit load transfer between components at generally high speeds and low friction.

When it comes to the efficient performance of machines at moderate to high speeds, a roller thrust bearing is used for it helps minimize wear and tear, energy consumption and noise. They are made to have designs, sizes, series and class clearance of international standards, which facilitate easy interchangeability, mounting and dismounting. To help you choose better, you can find these bearings in two types: radial and thrust bearings. Your selection however depends on the load you want the bearing to support, especially in applications that have loads acting primarily along axial shafts.

Find Different Types of Roller Thrust Bearings Suitable for Various Applications

A lot depends on the innate features of different thrust roller bearing types in case you want to choose a particular bearing for a specific application. It is essential to consider the load the bearing can handle at certain speeds to decide whether it is suitable for an application. The varying conditions under which it could operate is the next important thing to consider. You cannot however ignore the other essential factor of accommodating misalignment or shaft displacement. The following are the few commonly used roller thrust bearings that can take care of the considerations mentioned above.

Spherical Roller Thrust Bearing: This bearing is known for handling one-directional acting axial loads and acting radial loads simultaneously. For the purpose, a spherical roller thrust bearing has specially crafted rings and asymmetrical rolling elements, which assist in shifting the thrust between the raceways on the roller contact surface by the rolling elements atan “angle to the bearing axis”. The bearing’s flange design helps hold, as well as control the rollers.

Where there are applications that demand supporting misalignment while handling heavy loads, a spherical roller thrust bearing is highly preferred. The bearing allows some change in its design to suit certain applications under extreme conditions of high temperature and no possibility of the stoppage of machinery for maintenance.

Tapered Roller Thrust Bearings: They are known for occupying little axial space and having high stiffness. A tapered roller thrust bearing is used in applications, such as machine tools, trucks, material handling and buses, which ask for managing heavy axial loads, as well as peak loads.

You can still find many other types of this bearing; it is however advisable to choose the most appropriate roller thrust bearing that gives the best results.
