Testing Your Bearings

While bearings that have been damaged, broken, or worn do not always reveal themselves, it is better to be safe than sorry. Use your applications responsibly by testing the quality of your bearings with these easy tests.

Do A Visual Inspection

It is always a good idea to do a visual inspection of your ball bearings if you are in a position to do so. Checking for visual defects can help you repair, or know when to replace your bearings. Often times the root cause of a damaged or failing bearing is due to damaged seals. Once damaged, the seals allow moisture and dirt to enter and wear away the bearing. Some things to look and listen for when inspecting a bearing include:

1. Strange or unnatural noises

2. Discoloration

3. Flaking Along The Rolling Elements

4. Rust

5. Cracks

6. The Roller Bearing Does Not Spin Smoothly

7. There Are Foreign Objects Or Dirt In The Bearing

The Rocking Test

The rocking test is where the wheel bearing will be checked for quality by applying pressure to the top and bottom of the wheel. This creates a rocking motion on the wheel. If there is any open ended free play happening, this means the bearing is unstable and must be replaced.
