Thrust Bearings - Learning About the Different Types and Their Respective Applications

Thrust bearings are popular types of rotary bearings. They have the capacity to handle different radial loads. The bearing functions with the presence of needles, balls or rollers. Dimensions forming part of the consideration when seeking for such industrial products are outside diameters, overall width and bore. The industry making use of the product sets a particular standard or number system for bearings through the so-called metric diameter bores.

The search for the exact type of thrust bearing to be used in a certain process depends upon the bearing's rated speed, static and dynamic thrust load. When it comes to rated speed, those operating with the use of grease is slower than those bearings operating with an oil lubricant. The static thrust load is that property of a bearing to withstand a load without being deformed along the process. In order to understand more about the product, learn about the different types found on its list.

Ball bearings

These are types of bearings used in applications with lower friction and motion required. It consists of two types known as radial ball bearings and thrust ball bearings. The former is created for radial and thrust loads while the latter serves thrust loads. Radial ball bearings have inner and outer rings, cages and balls and are characterized by having ring races higher than the other.

Roller bearings

These are types of thrust bearings that can withstand greater loads than ball bearings. Among its subcategories, tapered roller bearings are popular. This roller bearing is formed by components such as the cone, cup, cage and tapered rollers.

Normal operating conditions dictate that the cone, rollers and cup take responsibilities when carrying the load as the cage is utilized to provide spaces as well as retain the cone rollers. These are highly favored in applications like power generation, mining, aggregate processing, oil fields, wind turbines and rolling mills.

Machine tool spindles, automotive transaxles, vehicle front wheels and trailer wheels make use of roller bearings as well.

Other types of thrust bearings

There are also fluid and magnetic bearings found on the list of thrust bearings. Fluid bearings are those that make use of a thin layer of gas or liquid to carry the workload. They are often smoother and quieter than roller bearings. Magnetic bearings on the other hand, makes use of magnetic levitation to carry a workload. They are often found in industrial machines like pumps, turbines, compressors and generators.
