O-Ring-Installation Damage Analysis

Situation:
There is a cut notch on the surface of the o-ring.

Reason:
1. The depth and width of the groove placed by the O-ring do not match the size of the o-ring.
2. The O-ring is cut by sharp parts or equipment.
3. Use O-rings with poor quality or low hardness.

Solution:
1. Pay more attention to the dimensional tolerance of O-ring when designing the groove.
2. The position of installing the O-ring should guide the sharp workpiece to the R angle, and the workpiece should be coated with high-viscosity lubricating grease before installation.
3. Carefully select the quality and hardness of the O-ring according to the use environment, action mode and working pressure.
