The DBH 8728/85 radial shaft seal is a single-lip seal that keeps oil or grease contained between a rotating shaft and its housing. It is used in gearboxes, pumps, electric motors, and transmission equipment to prevent leaks and block dust or water ingress. With a shaft diameter of 22.20 mm, housing diameter of 50.80 mm, and height of 10.80 mm, and featuring the Mx design, it fits assemblies where axial space is tight and dependable sealing is required.

This seal comes from the DBH brand and is identified by the code 8728/85. Its key dimensions are shaft 22.20 mm, housing 50.80 mm, and width 10.80 mm. The Mx design defines the lip and outer body geometry. As a single-lip radial seal, it retains lubricant and excludes contaminants in rotating equipment.

Typical applications include gearboxes, centrifugal pumps, electric motors, spindles, and transmission mechanisms—anywhere a shaft rotates inside a housing. It also appears in food, chemical, and process industry equipment when the lip material is compatible with the fluid and operating temperature. As a wear part, it should be replaced when leaks or dirt ingress are detected.

When selecting this seal, confirm that the shaft and housing dimensions match the assembly. The Mx design determines lip type and orientation, so consult the manufacturer's data sheet if unsure. During installation, lubricate the lip, avoid impact, and ensure the shaft is free of burrs or marks that could damage the seal. Thorough cleaning of housing and shaft extends seal life.
