Bearing size chart dimensions
Bearings come in a variety of different sizes, depending on the size of the shaft and the application requirements. Since they are used in all types of industries, they need to be sized for a variety of applications, from skateboard wheels to oil drill bits. How are these bearing sizes determined?
Here’s a simplified bearing size chart with common dimensions:
1.Width (W): This refers to the thickness of the bearing.
2.Inner Diameter (ID): This is the diameter of the inner ring of the bearing, where the shaft fits.
3.Outer Diameter (OD): This is the diameter of the outer ring of the bearing.
These are just a few examples of common bearing sizes, but there are many more available depending on specific requirements and applications. Always consult with a bearing manufacturer or supplier to ensure you get the right size for your needs.
Bearing Size Chart
| Bearing Type | Series | Inner Diameter (ID) | Outer Diameter (OD) | Width (B) | Load Capacity | Application |
| Deep Groove Ball Bearings | 6000 | 10mm | 26mm | 8mm | Light to Medium | Electric Motors, Fans |
| Radial Ball Bearings | 6200 | 12mm | 32mm | 10mm | Medium to High | Automotive, Machinery |
| Angular Contact Bearings | 7000 | 15mm | 35mm | 11mm | High Axial and Radial | Pumps, Machine Tools |
| Spherical Roller Bearings | 22200 | 20mm | 47mm | 18mm | Heavy Load | Mining, Heavy Machinery |
| Tapered Roller Bearings | 30200 | 25mm | 52mm | 15mm | High Radial and Axial | Gearboxes, Axles |
| Needle Roller Bearings | NK | 8mm | 16mm | 10mm | Compact, High Load | Compressors, Transmissions |
| Cylindrical Roller Bearings | N200 | 15mm | 35mm | 11mm | High Radial Load | Conveyors, Gear Drives |
Size depends on the size of the shaft and the application requirements. Bearing size greatly affects the performance and capabilities of a ball bearing; therefore, different sizes are used in different industries.
Generally speaking, smaller bearings have more limited load capacity. They are used in applications where space efficiency is more important than load capacity. Miniature bearings are typically constructed as precision bearings for extremely small applications such as medical instruments, robotics, or semiconductor equipment. Larger bearings, on the other hand, have greater load capacity. They are used in heavy-duty industries such as agricultural machinery, mining and drilling equipment, or heavy-duty power tools. NSAR also offers custom bearing size options for specific applications with unique requirements. Click to learn more about our high-quality ball bearings.
