In mechanical equipment, oil seals, also known as grease, fluid, or dirt seals, help keep lubricant from escaping by sealing the gaps between moving and stationary parts. Oil seals are essential parts of almost every kind of equipment and vehicle in use and have optional metric and inch shaft and bore sizes. To produce a tight seal, the sealing lipwhich is frequently composed of rubber or elastomerspresses up against the rotating shaft. Oil seals have optional single lip, double lip and triple lips. Depending on the temperature and chemical resistance requirements of the application, materials such as silicone rubber, nitrile rubber, or fluorocarbon are employed. Oil seals are relatively simple to install and replace, minimizing downtime for maintenance. Maxtran stocks both rubber covered and fully metal options for better structural support and to help secure the seal within the housing.
