Thrust ball bearings are used in industries such as aerospace, chemical industry and utilities. Thrust roller bearings are suitable for agriculture and other sectors that require high-load capacity.

Fortune Business Insights says the global ball bearing market size was USD 19.08 billion in 2019 and is projected to reach USD 21.90 billion by 2027.

As a global leader in the bearing industry, BMC provides custom solutions to lead your industry. We find solutions to get the bearing you need and reduce your long lead times. Whether that is a bearing that is modified, manufactured, or repaired to your specification, we can help you. In this article, we discuss thrust bearings, from designs to applications and more.

The types of bearings included in their forecast are self-aligning ball bearings, deep groove ball bearings, angular contact ball bearings, and others, as in thrust ball bearings.

Roller thrust bearings have higher load carrying capacities than ball thrust bearings. The higher speed applications require oil lubrication.

1. Contaminants - Contamination is one of the leading causes of bearing failure. Airborne dust, dirt, sand, and water are the most common ones that you run into, but chemicals and corrosives can also damage bearings.

The functions are to prevent the shaft from drifting in the axial direction and to transfer thrust loads applied on the shaft.

Thrust bearings include a variety of bearings that assists axial loads or axial force. It is an axial bearing that permits rotation between parts. Thrust bearings support the axial thrust of both horizontal and vertical shafts.

? What to look for: According to Bearing Failure: Causes and Cures, the most commonly found causes of misalignment include: bent shafts, dirt or burrs on the shaft or housing shoulders, shaft threads that are not square with shaft seats, and locking nuts with faces that are not square to the thread axis.

Radial bearings support the force that is applied vertically to the shaft. Thrust bearings support a force applied in the same direction as the shaft.

Thrust bearings are also commonly used in automotive and marine applications. They are used in cars because the forward gears in modern car gearboxes use helical gears, which, while aiding in smoothness and noise reduction, cause axial forces that need to be dealt with. [source]

Automotive, Industrial Machinery, Mining & Construction, Medical, and other industries such as Aerospace drive the market share.

?️ How to Fix it: Ensure you inspect shafts and housing regularly, use precision-grade locknuts, and shim the housings as needed.

Thrust bearings support a force applied in the same direction as the shaft. They can be categorized into two major types: Thrust ball bearing and Thrust roller bearing. The thrust ball bearings are used to deliver high performance, while the thrust roller bearings are typically used in applications where high load-carrying capacity is needed.

A thrust bearing, a type of rotary bearing, rotates between parts reducing friction and is designed to support an axial load (mostly in low-speed applications). It is the axial bearing that permits rotation between parts.

"Industrial Machinery is anticipated to have substantial growth owing to the moderate need for these bearings in rotating the shafts of several machines." [source]

There are various types of thrust bearings, each with its strength. The unique bearings deliver different performance and load capacity.

An axial or thrust bearing uses side by side races. The race on the side into which the shaft is inserted is called the shaft race. The race inserted into the housing is called the housing race. [source]

Machine failures are unpredictable and if you don’t have the backup bearings you need, you may be stuck with long-lead times, causing you to waste time and money.

There are preventative measures you can take to increase your bearing's lifespan and prevent improper wear on them. Read more from BDS, "What Causes Bearing Failures and Preventative Measures."

? What to look for: This may look like normal fatigue. You may see heaving rolling-element wear paths, evidence of overheating, and widespread fatigue areas.

When a bearing fails, it negatively impacts your facility, your reputation, and your bottom line. Regular preventive measures can keep your bearings at peak performance for as long as possible, saving your business time and money.

The most common materials used to produce thrust bearings are stainless steel and ceramic. The cage is made of brass or steel, depending on the application.

The force applied to a bearing is called the "load." There are the radial and axial loads applied to a bearing. The force applied vertically to the shaft is called the radial load, and the force applied in the same direction (parallel) as the shaft is called the axial load.

Thrust bearings are generally seated against a raised thrust collar around the shaft. The thrust collar allows the axial load to be transferred from the shaft to the bearing. Thrust bearings are typically used in pairs on each side of the thrust collar.
