Ball Bearing Sizes Chart: A Comprehensive Guide for Optimal Performance
Navigating the world of ball bearings can be daunting, especially when it comes to selecting the right size. Our Ball Bearing Sizes Chart provides a comprehensive breakdown of standard dimensions to ensure proper fit and optimal performance.
Selecting the Right Size
Ball Bearing Sizes Chart
| Inner Diameter (mm) | Outer Diameter (mm) | Width (mm) |
|---|---|---|
| 6 | 19 | 6 |
| 8 | 22 | 7 |
| 10 | 30 | 9 |
| 12 | 32 | 10 |
| 15 | 35 | 11 |
When choosing the correct ball bearing size, consider the following factors:
- Shaft or housing diameter: The inner diameter of the bearing should match the shaft it will be mounted on, while the outer diameter should fit snugly within the housing bore.
- Load capacity: The bearing size should be appropriate for the load it will bear, which is determined by the operating conditions and environmental factors.
- Speed: The higher the operating speed, the smaller the bearing size that can be used.
Benefits and Applications
Ball bearings offer numerous advantages, including:
- Low friction: Smooth operation and reduced energy consumption.
- High-speed capability: Can handle high rotational speeds.
- Load capacity: Supports both radial and axial loads.
How to Choose the Right Size
- Determine the shaft or housing diameter: Measure the shaft or housing bore.
- Calculate the load capacity: Use a load calculation formula or consult an engineer for guidance.
- Select the bearing size: Refer to the Ball Bearing Sizes Chart to find the appropriate size based on the diameter and load capacity.
Common Mistakes to Avoid
- Using the wrong size: Incorrect size can cause premature failure, increased friction, or noise.
- Overloading: Exceeding the bearing's load capacity can damage the bearing.
- Insufficient lubrication: Poor lubrication can increase friction and wear out the bearing prematurely.
