How to judge the quality of wheel hub oil seals

Appearance inspection: The surface of a high-quality wheel hub oil seal should be smooth and uniform, without cracks, bubbles or impurities.

Elasticity test: Gently press the edge of the oil seal. A high-quality oil seal should have good elasticity and be able to quickly return to its original state.

Heat resistance: Place the oil seal in a high temperature environment and observe whether it deforms or its performance deteriorates.

Oil resistance: Soak the oil seal in lubricating oil and observe whether it expands, softens or loses elasticity.
