❓Questions & Answers
Q1: What are the benefits of a double lip oil seal in large machinery?
A: The double lip structure provides dual protection — the inner lip keeps lubricant in, while the outer lip prevents dirt, water, and dust from entering. This is especially important in heavy-duty equipment that operates in dirty or outdoor environments.
Q2: Why is Nitrile Rubber (NBR) used for the lip material?
A: NBR is a widely used elastomer due to its excellent resistance to petroleum oils, fuels, greases, water, and many industrial fluids. It also retains flexibility and strength across a broad temperature range, ideal for sealing rotating shafts.
