Frequently Asked Questions (FAQ)
Q1: Why is a double lip oil seal better than a single lip?
A: The double lip design features two sealing edges—one to retain lubricant and the other to block dirt and moisture—providing superior sealing performance.
Q2: Why is Nitrile Rubber (NBR) commonly used in oil seals?
A: NBR is highly resistant to oils, greases, fuels, and wear, making it ideal for automotive and industrial sealing applications.
Q3: What operating temperatures can this oil seal handle?
A: This NBR oil seal performs effectively in temperatures ranging from -40°C to +120°C, suitable for most mechanical uses.
