Roller bearings and ball bearings are two different types of rolling bearings that differ mainly in the shape of the rolling elements.
Here are the main differences between roller bearings and ball bearings:
"We stock roller bearings from the brands FUD, NSK, RHP, SKF, FAG, INA, ZYS, KRW and many more.

What is the basic difference between ball bearings and roller bearings?
Shape of the rolling elements:
-
- Ball bearings: The rolling elements of ball bearings consist of balls.
- Roller bearings: Roller bearings use cylindrical or conical rollers as rolling elements.
Which rolling bearing should I use for radial and axial loads?
Load absorption:
-
- Ball bearings: Ball bearings are well suited for applications with high speeds and low to medium radial loads. They are less effective at absorbing very heavy radial or axial loads.
- Roller bearings: Roller bearings are able to support higher radial and axial loads than ball bearings. Due to their larger contact surface between the rollers and the rings, they are better suited for applications with heavy loads.
What is the difference between ball bearings and roller bearings in terms of friction and speed?
Friction and speed:
-
- Ball bearings: Due to their smaller contact surface, ball bearings generally generate less friction and are therefore suitable for high-speed applications.
- Roller bearings: Due to their larger contact surface, roller bearings generally generate slightly more friction, but are better suited to applications with higher loads.
Which ball bearing or roller bearing do I use for angular misalignment?
Self-alignment:
-
- Ball bearings: Some ball bearings, such as angular contact ball bearings and self-aligning ball bearings, have self-aligning properties and can compensate for slight angular errors, such as shaft deflections.
- Roller bearings: Some roller bearings, especially spherical roller bearings, are able to tolerate larger misalignments and therefore offer better self-alignment capability. Otherwise, they are less suitable for self-alignment.
"The choice between roller bearings and ball bearings depends on the specific requirements of your application. If you are dealing with heavy loads, roller bearings are often the better choice. However, for high-speed applications with light loads, ball bearings may be the preferred option. It's important to carefully select the right type of bearing based on load conditions, speeds and other factors.
