Thrust Ball Bearing – The Ultimate FAQ Guide

In rotating equipment, increasing the efficiency of axial load carriage is a difficult task.

Further, most equipment cannot handle high-speed thrust loads.

Thanks to thrust ball bearings, all tasks have been made much easier.

If you’re looking for further information about the ball bearing, its types, materials, installation process, and disassembly, the following FAQ will be helpful to you.

Here is a short guide to help you get started.

What Is Thrust Ball Bearing?

Thrust ball bearings are defined as a type of thrust bearing with a washer-like structure and deep grooves for the balls.

Thrust ball bearings are mainly designed to bear the thrust of the rotating equipment moving at high speeds.

The specialty of thrust ball bearing is that they can handle only axial loads, not radial loads. This particular nature is due to the distinguishing symmetry of these bearings.

Moreover, thrust ball bearings are available in flat seat thrust ball bearings and aligning seat ball bearings.

Both these ball bearings are classified according to the shape of the outer ring seat in their symmetry.

How Do Thrust Ball Bearings Work?

Almost all thrust ball bearings work by absorbing the axial loads from the moving rotating shafts into the integrated stationary housings.

Thrust bearings are also used to adjust the extent of axial loads transmitted in the linear direction of the shaft.

In addition to this, thrust ball bearings are also integrated into the power drills, where the mechanics adjust the weight into the rotating bill of the shaft.

Another method of the working of thrust ball bearings is by the absorption of the axial load, or more precisely called the thrust forces acting on the rotating body.

These bearings lower down the impact of the axial forces in the axial direction of the moving shaft.

What Are The Types Of Thrust Ball Bearings?

The significant types of thrust ball bearings are listed as under:

• Roller thrust ball bearings
• Fluid thrust bearings
• Magnetic thrust ball bearings
• Flat race thrust ball bearings

How Do You Use Thrust Ball Bearings?

You can use thrust bearings in the engines or turbines to support the axial loads parallel to the shaft.

Thrust bearings can hold the loads in the axial directions of the shaft. That is why they are known as axial bearings.

Moreover, you can also use the thrust ball bearings to retain the rolling elements in the rotating machinery.

The specialty of the thrust ball bearings to carry the axial load is due to the presence of two ring raceways.

Use Thrust Ball Bearings

Do You Grease Thrust Bearing?

Yes, you can grease the thrust ball bearing with high-quality greases to improve its performance and functioning.

The average power of the Thrust Bearing gradually reduces up to 50% with continuous movement. That is why you can grease the clutch thrust ball bearings to reduce the temperature.

In addition to reducing the temperature, greases are also famous for decreasing the oil flow in the thrust ball bearing.

This is why most active thrust ball bearings are available with directed lubrication by the manufacturer.

What Does A Bad Thrust Bearing Sound Like?

A bad or worn-out thrust ball bearing comes with an increased clearance between its rollers. The increased clearance is the primary reason for the rattling, squealing, or growling noises during operation.

In addition to such sounds, there are many other symptoms of bad thrust ball bearing. Some of these are included given as under:

• Pulsation 

A bad or worn-out thrust ball bearing will cause the pedal to vibrate or pulsate whenever it is pressed.

When the clutch is pressed, the damaged or bad thrust ball bearing will not distribute the load.

Thus, when you notice unusual vibrations or pulsations in the clutch while pressing it, note that your thrust ball bearing is not functioning correctly.

•  Clutch Sticking

Thrust ball bearings are known to lose their lubrication property after increased usage or when they start to wear out.

Thus, the decreased lubrication will make the bearing move more stiffly or bind at one place.

This will make it difficult for you to transmit the switch between gears.

Bad Thrust Bearing Sound

How Do You Fix A Thrust Bearing?

The steps for fixing the thrust ball bearings are described as below:

• Before fixing the thrust ball bearing, make sure to point the entire thrust ball bearing with mark points
• These marks at different parts of the thrust ball bearings will make it easy for you to arrange the bearing in a proper manner
• Don’t forget to mark the numbers of the retainers of outer and inner rings
• You can use two different colors to mark the shoes of the bearing so that the Babbitt material doesn’t get damaged
• Remove the clamp and outboard retainer rings of the thrust ball bearings
• Stick all the shoes to the thrust collar in alignment
• Remove the collar of the bearing very carefully without changing the position of the shoes
• Now remove the inboard retainer of the thrust collar in the same way
• You can use a lint-free rag to remove the oil film from the thrust collar and ring raceways
• Prepare the thrust collar with blue dyes
• Set the thrust collar in position to check the contact between the inner and outer raceways
• Make sure to place the thrust collar against the face of the inboard shoes

Another method to place the thrust ball bearing at the right position is to tap the crankshaft forward.

All these methods serve as the best solutions to place the main thrust bearing.

What Is A Thrust Bearing Made From?

All thrust ball bearings are made up of small bearing balls supported in a ring of the bearing. These bearings are used in low thrust applications to support the small number of axial loads.

In addition to this, thrust ball bearings are also made up of small cylindrical rollers arranged in the parallel axis pointing towards the axis of the bearing.

For thrust ball bearings, however, the bases materials are as follows:

• Stainless steel
• Ceramic
• Brass
• Polyamide

How Do You Lubricate Thrust Bearings?

You can lubricate the thrust bearings by different methods, which are given as below:

• Flooded Lubrication

This method involves fully flooding the parts of the thrust ball bearing in the lubricants. The lubricating oil is tilted at the top of the bearing’s channels and groves, where it is allowed to enter the parts of the bearing due to gravity.

• Direct Lubrication

This lubrication method involves using nozzles or oil jets to enter the fresh lubricating oil in each pad of the bearing’s surface.

• Tilt Pad Lubrication

Here is another method of lubricating the thrust ball bearings, which involves flooding the lubricant on the bearing with the help of an orifice or an outlet. These outlets will improve the proper flow of oil on the bearing while maintaining the pressure.

Lubricate Thrust Bearings

How Do You Preload Thrust Bearings?

The most common and easiest method of adding a preload to a thrust bearing is to use a wave spring.

The spring is used to act on the outer ring of the thrust ball bearings. This will cause the outer ring of the bearing to displace in an axial direction.

Another method to preload a thrust ball bearing is to hold the inner and outer rings of the bearings. You can do this by using the spacers or locking machines while adding the preload to the bearing.
