At a glance
Radial bearing
Designed primarily for loads perpendicular to the shaft axis; some types also accept axial load.
Choose when radial force dominates and the selected design covers any accompanying thrust.
Thrust bearing
Designed primarily for force along the shaft axis; radial capability depends on its specific design.
Choose for an axial-force path, with separate radial support if required.
Key differences
Typical design distinctions. The complete designation and current product specification take precedence.

| What to compare | Radial bearing | Thrust bearing |
|---|---|---|
| Primary force | Perpendicular to shaft | Parallel to shaft |
| Raceway orientation | Primarily radial arrangement | Axial washer or raceway arrangement |
| Combined load | Possible in suitable types | Possible only in suitable types |
| Direction | Axial capability varies by design | Single- and double-direction designs differ |
| Mounting | Ring fits and radial shoulders | Washers, support faces and axial retention |
| Selection | Resolve radial and axial forces | Check thrust direction and radial limitations |
Before you choose
- A radial bearing is not automatically incapable of thrust.
- A thrust ball bearing is not generally a radial bearing substitute.
- Allow the non-locating bearing position to accommodate shaft growth.
Check the actual model
Search a full designation, inspect its technical data, then compare candidate records. Similar names or dimensions do not guarantee interchangeability.
Filters show recorded catalogue attributes. Open each candidate to confirm its exact specification.
A few things worth clarifying
Are axial and thrust the same direction?
In bearing load terminology, both refer to force along the shaft.
What handles both radial and axial force?
Angular-contact, tapered-roller and some other designs can, within their specific ratings and arrangement.
