Bearing Analysis: Smearing
Condition
Surface is roughened and tiny particles adhere
Cause
Rolling elements slip in rolling motion and characteristics of lubricant are too poor to prevent slippage
Solution
- Select optimum lubricant and lubrication system capable of forming sound oil film
- Use a lubricant including extreme pressure additive
- Take precautions such as a small radial clearance and pre-load to prevent slippage
