What is a thrust ball bearing?

A thrust ball bearing is a type of bearing that has a specific use. It is used in many machines. Generally made of steel, it is designed to support only axial and light loads, unlike needle roller bearings or roller bearings.

Thrust bearings are made up of separable elements such as the shaft washer, housing washer, ball cage, etc. There are two types of thrust ball bearings:

  • The single-direction thrust ball bearing: has one row of balls and supports axial loads in one direction only.
  • The double direction thrust ball bearing: has a double row of balls and can support axial loads in both directions. This bearing has one shaft washer, two housing washers, and two ball cages.

How do thrust ball bearings work?

Thrust ball bearings operate by balls that rotate between two grooved rings. The balls are held in place by a cage, and the rings are usually steel or brass. The load is transferred from the shaft to the housing by the balls, which require lubrication to keep wear to a minimum.

What are the advantages and disadvantages of using a thrust ball bearing?

Thrust ball bearings offer several advantages over other types of bearings, such as increased resistance to axial load and wear. They are also relatively easy to install and maintain.

However, they cannot take radial loads and must be subjected to a certain minimum axial load to function properly.

How to choose a thrust ball bearing?

When choosing a thrust ball bearing, it is important to consider the application for which it will be used. Factors to consider include maximum load, operating speed, and ambient temperature. It is also important to choose the right size and type of bearing for your application.

Thrust ball bearings are available in a variety of sizes and types. Single-row thrust ball bearings are the most common type and are suitable for moderate loads and speeds. Double row ball bearings can handle higher loads but are not commonly used.
