Bearing Selection
Answer two or three questions and we will list the matching bearings for quick/preliminary bearing model selection.
Matching bearings
Bearing types covered
The wizard covers the seven standard rolling bearing types in our database. Each type answers a different load situation:
| Type | Best for |
|---|---|
| Deep groove ball | General purpose — radial load plus light axial load both ways |
| Angular contact ball | Combined radial and one-direction axial load |
| Self-aligning ball | Shaft misalignment or housing seating errors |
| Four-point contact ball | Axial load in both directions where space is tight |
| Cylindrical roller | High radial load at high speed; shaft free to float axially |
| Tapered roller | Heavy combined loads; usually mounted in pairs |
| Spherical roller | Very heavy radial load plus misalignment |
How the dimension series work
For the same bore, most types come in several dimension series. A larger series means a larger outside diameter and width — and higher load ratings. Example for deep groove ball bearings with a 20 mm bore:
| Series | Example (20 mm bore) | Dimensions | Character |
|---|---|---|---|
| 6000 | 6004 | 20 × 42 × 12 mm | Light, compact |
| 6200 | 6204 | 20 × 47 × 14 mm | Medium, general purpose |
| 6300 | 6304 | 20 × 52 × 15 mm | Heavy duty |
The wizard lists every matching model so you can compare series side by side — dynamic and static load ratings are shown as a range across the listed manufacturers.
