Angular Bearing – Ultimate FAQs Guide

Angular Bearing

Are you looking for Angular bearings and want to source some?

Or looking for some basic information before buying? If your answer is yes, then here is the complete guide.

Here in this FAQ guide, you will get the answers to the most basic to advanced level questions regarding angular bearings to help you get your decision correctly.

What Is Angular Bearing And Where It Is Used?

Angular bearings are used for both the radial and the axial load.

The angular bearings comprise an inner race ring and an outer race ring.

It also consists of several balls in contact with the inner race ring and the outer race ring.

These bearings are best to use where there is a need to bear a considerable amount of radial load or axial load or the combination of both these loads.

They are also perfect to use in machines where high speed is required.

Where It Is Used

Here are the uses of angular ball bearings.

• Angular ball bearings are best used in industrial segments.
• They are used in gearboxes and compressors.
• They are used in fans and windmills.
• They are used in turbines.
• These bearings are used in clutches and electric motors.
• These are best to use in high-speed applications.

What Is The Working Principle Of Angular Bearing?

In angular bearings, axially asymmetric races are used. 

The axial load in angular bearing passes in a straight line across the bearing.

On the other hand, the radial load passes in an oblique line across the bearing, and it sets apart the races axially.

This way, the axial race’s angle of contact and the radial race is the same. 

If the contact angle is higher, the higher axial load is assisted, but the lower radial load is assisted. 

The line that joins the point of contact of balls and a line perpendicular to the bearing axis is called the contact angle.

Angular bearing bears the axial load in both directions as well as the radial load.

Where Can You Buy Good Quality Angular Bearing At A Reasonable Price?

You can resolve this issue by customizing your product. 

Chinese manufacturers will customize your product as you want with precision.

Do Angular Bearing Need Lubrication? If Yes, What Type Of Lubrication Is Needed?

Angular bearing is used in machines where high speed is required, so these bearings need to be properly lubricated.

These bearings can be lubricated in two ways.

Grease Lubrication

Commonly these bearings are lubricated with the help of grease lubrication.

The amount of grease can affect the performance of the bearing, so you should fill the bearing with the right amount of grease.

To lubricate the angular bearing properly and correctly, you should have a piece of proper knowledge about the free space of the angular bearings.

The angular bearings have different types, and you can easily find a complete guide about the free space of each type.

Suppose you do not grease the angular bearing properly. 

In that case, it can affect the bearing when the temperature rises. 

High temperature can also have a bad impact on the durability of the angular bearing.

Solid Oil

Sometimes the angular bearings are lubricated with solid oil. 

There is a risk of contact of the bearing directly with water and any other problematic material.

Solid oil means that the oil-saturated in the polymer material. 

Then the polymer material is molded to form a bearing. Still, a very narrow gap is left between the balls of the bearing.

This type of lubricated angular bearings has many micro-pores. 

All of the free space in the angular bearing is approximately filled.

The oil is released when the bearing is operating.

The solid oil-lubricated angular bearings are lubricated once in their lifetime. 

There is no need to lubricate them ever again.

You can get both types of bearings from LLG bearing.

Angular Ball Contact Bearing

In Which Types, Angular Bearing Comes In?

There are three types in which angular ball bearings come in.

Single Row Angular Ball Bearing

Single row angular ball bearings support axial load in one direction.

Generally, a single row angular ball bearing is placed with a second bearing. 

These bearing rings have an upper and lower shoulder that cannot be separated.

Variants

The variants of single row ball bearings are.

• Open variant.
• Sealed variant.

Benefits

Here are the benefits.

• These bearings can carry heavy loads.
• These bearings also support fast accelerations and decelerations.
• These bearings have easy mounting, which means there is no need for adjustment for preload.

Double Row Angular Bearing

Double row angular ball bearings are like two single row angular ball bearings that are placed back to back to each other.

There are two rows of balls in the angular ball bearing.

Variant

The variants of the double row angular bearings are.

• Open variant.
• Sealed variant.

Benefits

Here are the benefits.

• These bearings require less axial space.
• Angular ball bearing supports radial and axial load in both directions.
• Also, support tilting movements.
• Double row angular bearing has a stiff bearing arrangement.

Four Point Contact Bearing

Four-point contact bearings are the radial single row angular bearing with the raceways of the bearing designed in such a way that it supports the axial load in both directions.

Benefits

Here are the benefits.

• Assist axial load in both directions.
• Separable design.

What Is The Size Range Of Angular Bearing?

Here is the size range of all three types of angular bearing.

Single Row Angular Bearing

Here is the diameter of the bore.

1. B50: 10 to 65mm
2. B60: 70 to 120mm
3. B66: 130 to 200mm

Double Row Angular Bearing

Here is the diameter of the bore

1. B70: 10 to 85mm

Four Point Contact Bearing

Here is the diameter of the bore.

1. B72: 30 to 200mm

What Kind Of Loads Can An Angular Bearing Support?

Angular bearings are used for supporting combined loads, radial and axial load acting simultaneously.

The load-carrying capacity of the axial load of the angular bearing increases with the increase in the contact angle.

The radial load is applied on a single row angular bearing; the additional axial load is generated and applied to the relative reverse load.

Double row angular bearings support both the heavy axial and heavy radial loads in both directions.

It also supports the axial and radial combined loads and moment loads but chiefly the radial loads.

As the bearing largely supports the radial load, it will lessen the axial movement of the shaft.

 Angular Bearing With Different Sizes

How To Select A Particular Type And Size Of Angular Bearing For Your Product?

Here is the guide about choosing a particular type and size of the angular bearing by LLG bearing. 

Type Of The Bearing

Following are the factors that you should keep in mind.

1. First of all, which type of load or the combination of the loads that the specific type of angular bearing can support.
2. The rotation speed is another factor that you have to consider. Angular bearings are best to use for high speeds.
3. Which bearing is suitable for misalignments, such as the double row angular bearing, is unsuitable for misalignment.
4. Consider the environment in which your bearing is going to be used. 

Like there are some environments in which there is a chance of direct contact of bearing with the water.

For such conditions, solid oil-lubricated bearings are used. 

1. The sealing system of the bearing plays a vital role, so consider it too. 

Suppose there is a chance of any type of contamination of the bearing. In that case, the sealed variant of the bearing is preferred to ensure the durability of the bearing.

Size Of The Bearing

Few things to consider while choosing the right size of the angular bearing.

1. First of all, the size of the bearing should be such that it can bear the required amount of load.

It is known as the static load. 

In this, the permanent deformation of the angular bearing is considered when a larger load than capacity is applied.

So the static load for the specific size of the angular bearing is calculated before avoiding any mishap.

1. The other thing that is linked to the size of the bearing is the service life of the bearing. 

It means whether the bearing can give the expected output or not. 

This is called the rating life.

In this, several working conditions and expected fatigue of the bearing is determined to avoid any inconvenience.

Single Row Angular Bearing

How To Increase The Life Time Of Angular Bearing?

Following are the tips to keep in mind to increase the lifetime of angular bearing.

1. The installation of the bearing is of prime importance. 

To install the bearing properly, you should do it in a clean environment and a clean tool to avoid contamination.

1. To avoid any impurities contaminating it after installation, you should avoid using any old seals and old parts of the bearing.

Lubricate the bearing properly with the right lubricant. 

You will know about the right lubricant by reading the manufacturer’s manual.

1. There will be other instructions on the manufacturer manual like when to lubricate the bearing, when to clean the bearing, and when to repack the bearing.
2. Choose the right size and high-quality angular bearing.

Angular bearings are meant to operate higher, so you should focus on the quality of the bearing to avoid early damage or failure of the bearing.

Focus on the high-quality material of the bearing and corrosion-resistant bearing like the angular bearings from LLG bearing.

Are Angular Bearings Worth It?

Yes, angular bearings are definitely worth the price.

Many people are hesitant to buy angular bearings as they are a bit costly and require maintenance.

But these bearings can accommodate both axial and radial load better than any other bearing.

Angular bearings can bear more heavy loads than other bearings of the same size.

Angular ball bearings are best to use in machines that require high speeds.

What Is The Actual Purpose Of Angular Bearing?

Angular bearings are used in many machines and types of equipment. 

Still, they are exclusively used in machines where the following factors are included.

• Angular bearings are used in machines and types of equipment where a large thrust load is involved.
• It is used in machines where a combination of radial and axial load is applied.
• These are used in machines operating at high speeds.

Double Row Bearing

What Are The Benefits Of Using Angular Bearings?

Here are the advantages of angular bearings

1. The angular bearing can bear both radial and axial loads.
2. Greater the contact angle of the angular bearing higher is the axial load-carrying capacity of the bearing.
3. These bearings work smoothly at extremely high speeds.
4. Angular bearings provide high precision.
5. At a certain angle, the load in the angular ball bearing is shifted from one ring to another.

Are Angular Bearings Directional?

Single row angular bearings can only support axial load in one direction.

On the other hand, the double row angular bearing supports the axial and the radial load in both directions.

Which Way Do Angular Bearings Go?

The angular bearings can support the load in only one direction only. 

Still, they can be built at different contact angles.

This angle can range from 0 to 45 degrees, and this way, the load on the bearing can be transferred.

Double Row Angular Bearing

Are Double Row Angular Bearing Preloaded?

For angular bearing, it is crucial to preload them.

So the double row angular bearings are preloaded.

For double row angular bearing small load is required for the high speed, and a large load is required for the low speed.

The preload of the double row angular bearing is slightly smaller or equal to the working axial load.

Choosing the right preload is very important for double row angular bearing as it can affect the service life of the bearing.

What Are The Differences Between Deep Groove Ball Bearing And Angular Ball Bearing?

The differences between the deep groove ball bearing and angular ball bearing are given below.

1. The angular bearing has one shoulder on both sides of the outer rings.

While the deep groove ball bearing has a double shoulder on both sides of the outer ring.

1. In deep groove ball bearings, there is outer ring groove curvature.

On the other hand, the outer ring of the angular bearing is larger than the deep groove ball bearing.

1. Angular ball bearings are suitable for radial load and larger axial load. 

If a pair of angular ball bearings is used, it can accommodate the load in both directions.

Deep groove ball bearing is suitable for small radial and axial loads.

1. The maximum speed limit of the angular bearing is higher than the speed limit of the deep groove ball bearing of the same size.

How To Install Angular Bearings?

A complete procedure to install the angular bearings properly by LLG bearing.

Clean Environment

When you are going to install the angular bearing, the environment should be clean. 

Slight contamination can affect the life of the angular bearing.

Do not open the bearing days before the installation; instead, open it on the installation day.

It is best to use gloves and hairnets to avoid any contamination.

Using The Right Tools.

Using the right tools for the installation of the bearing is crucial.

If you are using the wrong tools, it can damage the races or deform the bearing.

This deformation can result in a decreased life span of the bearing and performance of the bearing.

A Proper Technique Should Be Used

Sometimes the inner race of the bearing is slightly heated to directly slide the bearing on the shaft without using any other tools.

There is a heating limit of the bearing which should be taken care of while using any heating.

If the induction heater cannot be used, then an arbor press is used.

Through the arbor press, you can slide the angular bearing on the haft in one press.

Tools like hammers that can damage the bearing should never be used.

If only the hammer is available, then you should only use the dead-end hammer.

Factors To Consider

Know about the amount of preload that is suitable to achieve the desired speed.

The angular bearing size matters as the life and the working capacity of the bearing depend on it.

Know about the load capacity of the bearing and how much load the bearing has to bear.

Tolerance Of The System

Tolerance plays a crucial role in the life of angular bearing.

Tolerancing is considered an important factor, especially for high-speed devices.

Ball Bearing

What Are Angular Bearing Bottom Brackets?

The angular bearings are mainly manufactured for the bottom brackets. 

The bottom brackets hold a pair of angular bearings in the bearing holding cups. 

And then, a spindle attaches the cranks and the bearing holding cups.

The angular bearing bottom bracket is used in bikes

The angular bearing bottom brackets are always in use when the bike moves, so the bottom bracket should be high quality.

It is best to update the bearing bottom brackets regularly.

What Are The Differences Between Radial And Angular Bearing?

The difference between the radial bearing and the angular bearing is as follows.

1. As the name indicates, the radial bearing only supports the radial load.

On the other hand, the angular bearing supports radial and axial load in both directions.

1. The angular bearing offers a much higher load rating than the radial bearing.
2. Angular bearings are considered to be more durable than radial bearings.
3. Suppose there is the slightest change in the preload of the bearing. In that case, it can affect the life of the angular bearing, and the angular bearing will wear off at a higher rate than the radial bearing.

But the preload in the radial bearing does not affect the life of the bearing that much as compared to the angular bearing.

How Are Angular Bearing Arranged?

Double Row Angular Bearing In Vertical Position

Here is the arrangement of the two types of bearing.

Single Row Angular bearing

The single row angular bearing can be arranged back to back, face to face, and tandem mounting.

Specifically, single row angular bearings are manufactured in such a way to be mounted in the machine where two single row angular bearings can be placed side by side randomly.

Double Row Angular Bearing

Double row angular bearings are ordered consecutively.

The double row angular bearing looks like two single row angular bearings. 

Still, they are narrower than the single-row angular bearing.
