Zusammenfassung:	The utility model provides an axel shaft oil seal which comprise a metal frame and a rubber body. An oil seal is formed by the metal frame and the rubber body. A main lip opening is arranged at the bottom of the inner lateral side of the oil seal, an oil seal spring is arranged on the outer lateral face of the main lip opening, and a dust-proof opening is arranged on an air lateral face of the oil seal. The perpendicular distance between the main lip opening of the oil seal and an A surface ranges from 3.7mm to 4.1mm, and the thickness of the section at a waist position ranges from 0.8mm to 1.2mm. The minimum of the tensile stress of the oil seal spring ranges from 1.47N to 1.94N, and the maximum of the tensile stress of the oil seal spring ranges from 2.03N to 2.63N. The rubber body, the oil seal lip opening and the dust-proof opening are made of fluororubber. The axel shaft oil seal has the advantages of improving anti-eccentric capacity, fast filling gaps caused by big eccentricity, and having good followi
