Small lines bearing Cause of failure
About failures of miniature ball bearings 40% is the of contamination by dust, dirt, debris And corrosion caused. Pollution is usually caused by the incorrect use and poor use of the environment, It also cause torque and noise problems.By the environment and the pollution generated by the micro-bearing failure can be prevented, But can be determined by simple visual observation is generated such failure reason. Reasonable as long as the use and install, The miniature bearings denudation is easy to avoid.
The Small lines bearing denudation is easy to avoid. The denudation feature in the the miniature bearing ring raceway indentation left by the impact load or improper installation. The denudation usually occurs when the load exceeds the material yield limit. If not properly installed so that a load across the the miniature bearing ring will produce erosion. The miniature bearing ring indentation also produce noise, vibration and additional torque.
