Bore Diameter: 35mm, Outer Diameter: 50mm, Width: 8mm. Good Oil and Fuel Resistance. High Tensil Strength. Low swelling in Water. Good heat resistance in 120º C in Oil. NRB Temperature Range: -40º - 120º C. Double lip design: The oil seal adopts a double lip design with a main sealing lip and an auxiliary sealing lip. The main sealing lip is responsible for sealing the lubricating oil, while the auxiliary lip provides additional dust protection to prevent the entry of light dust and liquid contaminants. Skeleton structure: TC skeleton oil seals are composed of a single metal skeleton and rubber coating. This structure provides good elasticity and durability, while the skeleton design helps to maintain the shape and stability of the oil seal. Spring loading: The oil seal has a built-in spring to ensure constant pressure between the sealing lip and the shaft, and can maintain effective sealing even when rotating at high speed or the oil seal material is compressed and deformed due to wear., Manufacturer: OTOTEC
