description The utility model relates to a sealing element, particularly to a combined oil seal. The combined oil seal comprises an inner oil seal and an outer oil seal which are mutually combined; and the inner oil seal consists of an inner framework and an inner seal element, and the outer oil seal consists of an outer framework and an outer seal element. The combined oil seal is characterized in that an axial displacement surface is arranged at the contact of the inner framework and the secondary lip of the outer oil seal; and one main lip of the inner oil seal and two secondary lips of the inner oil seal are arranged in the inner seal element. The combined oil seal has excellent dust prevention effect, can prevent dust, sand and mud from entering, avoids the abrasion of the inner lip, prolongs the service life of the oil seal, and meet the requirements of actual condition.
