Information

In terms of material, we offer two options: nitrile rubber (NBR) and fluorocarbon rubber (FKM). NBR-based SB-type oil seals feature excellent mechanical properties and superior wear resistance, making them suitable for most standard operating environments.

They operate within a temperature range of -40°C to 120°C and effectively withstand various media such as mineral oil, synthetic oil, and grease. In applications like automotive engines and industrial gearboxes, they provide long-term, reliable protection against fluid leakage. FKM-material oil seals stand out for their exceptional high-temperature resistance and chemical corrosion resistance, with an operating temperature range of -26°C to 250°C. They are an ideal sealing solution for high-temperature equipment in industries such as chemicals and power generation. In harsh chemical environments, such as the sealing areas of chemical pumps and reactors, they maintain excellent sealing performance to ensure safe equipment operation.

Additionally, SB-type oil seals demonstrate exceptional radial stiffness, particularly in larger sizes. Even under significant pressure, they maintain stable shape and sealing performance, effectively preventing rebound caused by pressure. These outstanding performance characteristics make it widely applicable in fields with extremely high requirements for sealing reliability, such as heavy machinery and aerospace equipment, providing a solid foundation for efficient equipment operation. It significantly reduces equipment failures and maintenance costs caused by sealing issues, making it the top choice for users seeking exceptional sealing performance.
