The DBH 8681 oil seal is a single-lip radial shaft seal, designed to retain lubricant and exclude contaminants on rotating shafts. Its standardized dimensions —57.20 mm shaft diameter, 82.50 mm housing diameter and 9.50 mm height— make it suitable for assemblies where axial space is limited. It is manufactured with elastomer resistant to oils and greases, and its Mx-R-AH design incorporates an auxiliary lip that improves sealing under severe conditions. It is a common replacement part in pumps, electric motors and gearboxes.

This DBH 8681 oil seal has a shaft diameter of 57.20 mm, a housing diameter of 82.50 mm and a height of 9.50 mm. Its Mx-R-AH design combines a main sealing lip with an auxiliary exclusion lip, offering a double barrier against dust and particles. The outer body is made of elastomer, and the sealing lip runs on the shaft with controlled interference to ensure sealing. It is a component of the radial shaft seal category, intended for rotating shafts with moderate peripheral speeds.

Typical applications of this oil seal include centrifugal pumps, electric motors, gear reducers and gearboxes, where oil or grease must be contained and dirt ingress prevented. It is also used in power transmission equipment, such as bearing supports and spindles. Its compact size makes it suitable for assemblies where radial and axial space is limited, and its design with an auxiliary lip is useful in environments with dust or moisture.

To correctly select this oil seal, verify that the shaft and housing dimensions match those indicated: 57.20 mm and 82.50 mm respectively. The 9.50 mm height must be compatible with the housing depth. During installation, lubricate the lip with the same oil or grease used in the equipment, and insert the oil seal perpendicularly to avoid damage. If the shaft shows wear, consider a neighboring size or an oil seal with a wider lip.
