Practical bearing guide
Deep Groove vs Angular Contact
Compare deep groove and angular contact bearings: load capacity, speed, contact angle, and when to use each.
Deep groove ball bearings and angular contact ball bearings look similar but serve different purposes.
Deep Groove Ball Bearings
- Single row, Conrad-type assembly.
- Handle primarily radial loads with moderate axial capacity in both directions.
- Higher speed capability than angular contact.
- Most common: 6200, 6300 series for electric motors, pumps, fans.
- Lower cost, wider availability.
Angular Contact Ball Bearings
- Raceways designed with a contact angle (15deg, 25deg, or 40deg).
- Handle combined radial and axial loads; axial capacity in one direction only.
- Often used in matched pairs (back-to-back, face-to-face, or tandem).
- Common: 7200, 7300 series for machine tool spindles, high-speed pumps.
- Higher precision grades available (P5, P4).
When to use which
| Condition | Choose |
|---|---|
| Electric motor, pump, fan | Deep groove (6200) |
| Machine tool spindle | Angular contact pair (7200) |
| Axial load one direction only | Angular contact |
| Lowest cost replacement | Deep groove |
| Highest speed | Deep groove (less contact friction) |
If you are replacing an angular contact bearing, note the contact angle and arrangement before ordering.
Still unsure which model fits?
Ask for a model check Send the old bearing marking, dimensions, quantity, and application for a manual check.
