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.

Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of the balls. They also have non-separable rings. Their straightforward basic design has many advantages:
- Excellent for high speeds
- · Good radial load capacity
- · Acceptable axial load capacity in both directions
- · Have low torque capacity at startup and running speeds
- · Can operate with low noise
- · Require little maintenance
As flexible as the performance is, the configurations of single row ball bearings is also as versatile. These bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the outside edge. While many different retainers are available, pressed steel cages are most commonly used. Even tapered bores are available upon special order.
Single row deep groove ball bearings come in three numerical series representing the size and load capacity of each. They are:
- 6000 Series - Extra Light Ball Bearings– Ideal for limited space applications
- 6200 Series - Light Series Ball Bearings– Balanced between space and load capacity
- 6300 Series - Medium Series Ball Bearings– Ideal for heavier load capacity applications
