Oil seals play a vital role in the efficient operation of machinery and equipment by preventing the leakage of oil or other fluids. One commonly used type of oil seal is the 65x90x10 oil seal, which is designed to fit a specific shaft size of 65mm, an outer diameter of 90mm, and a thickness of 10mm. These seals are typically made from rubber or other flexible materials that can withstand the harsh conditions often found in machinery.

Oil seals, which are also known as rotary shaft seals, fluid seals or grease seals, play an important role in closing down the gaps between moving and stationary elements of mechanical equipment.
