- Oil seals, also known as shaft seals or grease seals, are essential components used to prevent lubricants from escaping and contaminants from entering a machine. They are commonly found in vehicles, industrial equipment, and household appliances. Without oil seals, machinery would quickly wear out and break down due to insufficient lubrication and contamination.

Oil seals are made out of nitrile synthetic rubber with steel stiffener rings. Other rubbers such as viton, silicon, neoprene or poly acrylic can be used for specific applications. The stiffener rings may be stainless steel or brass where highly corrosive fluids are to be sealed. Springs are generally made of spring steel to IS: 4454:Gr.ll or from stainless steel or bronze for corrosion resistance
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

Proper installation and maintenance of oil seals are essential to ensure optimal performance and longevity. Before installing a new oil seal, it is important to clean and inspect the shaft and seal housing for any damage or debris that could affect the sealing performance. Additionally, applying a thin layer of lubricant to the seal lip can help improve sealing efficiency and reduce friction during operation.
