The DBH 8681 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 made with elastomer resistant to oils and greases, and its Mx-R-AH design includes an auxiliary lip that improves sealing under severe conditions. It is a common replacement part in pumps, electric motors and gearboxes.

This DBH 8681 seal has a 57.20 mm shaft diameter, an 82.50 mm housing diameter and a 9.50 mm height. 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 tightness. It is a component of the radial shaft seal category, intended for rotating shafts at moderate peripheral speeds.

Typical applications for this seal include centrifugal pumps, electric motors, reducers and gearboxes, where oil or grease must be contained and dirt kept out. 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 select this seal correctly, check 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 seal perpendicular to avoid damage. If the shaft shows wear, consider a seal with a wider lip coverage.
