At a glance
Angular-contact ball
A defined contact angle lets the bearing carry combined radial and axial load.
Choose when radial support and controlled axial stiffness are required in the same bearing arrangement.
Thrust bearing
The family includes thrust ball, cylindrical, needle and spherical roller designs with different radial capabilities.
Choose for the required axial load path, direction and support geometry.
Key differences
Typical design distinctions. The complete designation and current product specification take precedence.

| What to compare | Angular-contact ball | Thrust bearing |
|---|---|---|
| Primary role | Combined load | Axial load |
| Radial support | Part of suitable angular-contact designs | Not available in every thrust type |
| Axial direction | Single-row design primarily one way | Single- or double-direction designs |
| Preload | Often specified for pairs | Depends on exact thrust design |
| Mounting envelope | Radial rings and angled contacts | Shaft/housing washers or axial raceways |
| Selection check | Contact angle, pairing and axial setting | Thrust type, direction, speed and radial limits |
Before you choose
- Thrust ball and spherical roller thrust bearings have different radial-load abilities.
- Do not use the generic word thrust to select a calculator's bearing factor.
- Minimum axial load requirements can matter at speed.
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
Can a thrust ball bearing replace an angular-contact bearing?
Usually not directly: the radial load path and mounting geometry differ.
Does a larger contact angle turn a bearing into a thrust bearing?
Classification and allowable loads follow the complete design, not one angle threshold alone.
