How Does a Thrust Bearing Work?

 

One of the most important components in any machine that moves is a bearing. A bearing is a traditionally circular shaped part designed to restrict the movement of other machine components. Furthermore, bearings reduce the friction that comes with metal moving against other metal surfaces. As such, bearings are essential for preserving the longevity of machines. There are many different types of bearings, and one of the most important is a thrust bearing. A thrust bearing is a bearing specifically designed to support components that rotate. In more technical terms, a thrust bearing is any bearing designed to support an axial load. There are many different types of thrust bearings, each of which function a little bit differently from each other. Even so, we hope to explain how a few of the most common thrust bearings work, and explain why they’re so important.

How do the Most Common Thrust Bearings Work:

A thrust bearing primarily works by limiting which directions a moving machine part can turn. Most often, thrust bearings restrict moving machine parts to rotating in a circular direction, though these bearings can also be used to only restrict horizontal or vertical movement. By restricting movement, all thrust bearings serve the same main function. They are designed to reduce the friction between moving metal parts and prevent machine damage from parts moving in the wrong direction. This is true of all thrust bearings, no matter what type of thrust bearing they are. Even so, different thrust bearings accomplish their purpose in different ways. Depending on your machine, it may require one of the following types of thrust bearings:

• Ball Thrust Bearings: One of the oldest and most basic thrust bearings systems.These thrust bearings have tiny balls in the perimeter of the bearing. This is one of the most common types of thrust bearings, and is particularly effective for small machines or those made with inexpensive components.
• Cylinder Thrust Bearings: As the name suggests, this thrust bearing is made up of a cylinder shaped roller. It is specifically designed to accommodate much heavier axial and impact loads compared to ball thrust bearings. Automobile crankshafts are almost universally made with cylinder thrust bearings.
• Magnetic Thrust Bearings: One of the most advanced thrust bearing systems, magnetic thrust bearing use magnets for maximum machine support within minimal friction. This is especially useful for machines that would be complicated by oil interaction, and is often used in generators and other electronic machines.

What Machines Use Thrust Bearings:

Almost everyone modern machine with moving parts will use thrust bearings of some kind. They’re easy to mount, while offering fantastic strength, durability, and reliability to significantly increase the longevity of the machines they’re incorporated into. Furthermore, thrust bearings can be used in extreme environments, and can support high loads when incorporated correctly. Some of the most popular and important machines that rely on thrust bearings include:

• Automobiles
• Airplanes
• Mining equipment
• Oil rigs
• Home appliances
• Air conditioning systems
• Generators
• Turbines

Get Thrust Bearings Built to Last At Atlas Bronze:

A good thrust bearing can add years to the functional lifespan of a machine. Even so, a thrust bearing won’t do much if the bearing itself is made poorly. There are also other components to be aware of, such as the washers that will help a bearing stay in place despite the heavy movement and axial loads it will have to sustain.
