Standard ball bearing sizes are defined by international standards such as ISO and ABMA. These standards ensure compatibility and interchangeability among bearings from different manufacturers.
| Size Range | Inner Diameter (mm) | Outer Diameter (mm) | Width (mm) |
|---|---|---|---|
| Extra Small | 1-10 | 15-30 | 6-12 |
| Small | 10-20 | 30-60 | 12-24 |
| Medium | 20-40 | 60-100 | 24-40 |
| Large | 40-80 | 100-160 | 40-60 |
| Extra Large | 80-120 | 160-200 | 60-80 |
Factors to Consider When Selecting Ball Bearing Sizes
Choosing the right ball bearing size depends on several factors, including:
| Factor | Considerations |
|---|---|
| Load Capacity | The bearing must be able to withstand the expected loads. |
| Speed | The bearing must be suitable for the operating speed. |
| Available Space | The bearing must fit within the available space. |
| Housing Type | The bearing must be compatible with the housing design. |
