Roller Bearing Vs Ball Bearing Differences

If you wish to have some basic idea about roller bearing vs. ball bearing you are perhaps in the right place. Though we must have certainly come across roller bearing and ball bearing, we may not be aware of the main differences between the two.




When you look at them, superficially you may not be able to find much difference. However in spite of similar looks they have different uses. Over the next few lines, we will try and find out the major differences between the two.

How Do Bearings Work

The mechanics of bearing are the same. They come with a ball which is set within an external or internal ring. When this happens, it allows the force to be applied to the ball. This is often referred to as loading. Loading can be of two types, radial loading and thrust loading.

When you choose radial load, it means that the bearing will roll or rotate when it is under tension. On the other hand, when you use a thrust load, it will be subject to force depending on the angle at which the thrust is being given. Bearings have been around for centuries and are used for rolling, pulling and other such functions.

Basic Difference between Ball Bearings and Roller Bearings

Ball bearings are used for smaller jobs such as for rotating wheels and hard drives and other day to day applications. However, the problem with ball bearings is that they cannot withstand pressure and they could either become deformed or break.

However, when the load is light and within manageable limits then can handle both radial and thrust functions. That is the main reason why they are popular with engineers. The main job of a ball bearing is to transfer the weight and ensure that is gets moved to the inner raceway from the outer raceway. This ensures that the object spins smoothly.

On the other hand, when we talk about roller bearings we are looking at something which will be able to handle heavy loads. They are usually housed in a cylinder. Hence, they are in a much better to distribute load to a much larger area even when heavyweights are carried by them.

It is the type of use which would differentiate between the ball bearing and roller bearings. Both have their unique uses and properties, and it is the end use which matters the most.

Automotive sector boost The Demand for Ball and Roller Bearings

Image
Allowing for great versatility and flexibility, bearings are used in every  industry  that involves motion. That is to say, virtually every kind of machinery or equipment — everything from household appliances and automobile parts to aerospace and defense equipment — makes use of bearings or is made with equipment containing bearings. There are two primary types of bearings: roller bearings and ball bearings. Cylinders Roller bearings  use cylinders to maintain separation between moving parts.  Ball bearings , on the other hand, utilize balls to separate the shifting pieces. Both roller bearings and ball bearings are designed to reduce rotational friction while supporting axial and radial loads. Ball bearings operate at higher speeds than roller bearings and can handle moderate radial and axial loads. Roller bearings can achieve relatively high speeds, but are specifically designed to carry heavy radial loads. Common Bearing Applications and Uses Bearings are uniqu

Angular contact ball bearings applications

Image
Angular Contact Ball Bearings  are used in a variety of applications and equipments yet these bearings are exclusively designed and developed for carrying high radial and axial load capacities for a long time. There are three types of Angular Contact Ball Bearings, single row bearings, double row bearings and four point contact ball bearings. Besides the difference in their design and structure, they also have different applications and properties. Single row bearings are used to deliver high thrust in one direction while the double row bearings come with high thrust capacity in both directions. Design Attributes of Angular Contact Ball Bearings Angular Contact  Ball Bearings  consist of an inner ring, outer ring, balls and the cage that holds those balls at a specific angle. Because of the specific angle and geometry of both rings and their shoulders, Angular Contact Ball Bearings deliver high axial load capacity. There are many additional design attributes and options a
