crankshaft oil seal 102

The crankshaft oil seal 102 is a critical engine sealing component that prevents oil leakage around the crankshaft area. It is typically manufactured from heat-resistant NBR rubber or silicone and reinforced with a metal layer for added strength. The inner diameter of this seal is 102 millimeters, while the outer diameter varies between 120 and 135 millimeters depending on engine design. Its thickness usually ranges from 10 to 15 millimeters, and it can withstand oil pressures up to 5 bar. The sealing lip is designed with a multi-lip profile to ensure stable performance at crankshaft speeds up to 3000 RPM.

The crankshaft oil seal 102 operates within a thermal range of -40 to +200 degrees Celsius, making it suitable for heavy-duty engine conditions. The inner surface is reinforced with anti-friction additives to minimize wear and extend service life. Under standard conditions, the estimated lifespan of this component exceeds 7000 working hours. Using a high-quality crankshaft oil seal helps reduce oil consumption, prevent leakage-related emissions, improve overall engine efficiency, and protect the lubrication system from severe failures.
