For rotating shafts that need reliable sealing, the DBH 5686 radial shaft seal is a lip seal that fits on the shaft and inside the housing to retain lubricant and block contaminants. It measures 31.75 mm shaft, 53.97 mm housing, and 11.11 mm width, with Mz design. MR Industrial Accessories supplies this brand and helps you select the right seal for your application.

The DBH 5686 seal, identified by designation 5686, is a radial shaft seal with a sealing lip and metal body, known as Mz design. Its nominal dimensions are shaft 31.75 mm, housing 53.97 mm, and width 11.11 mm. This component works in direct contact with the shaft and the cavity, so proper selection depends on the actual dimensions of your assembly.

Radial shaft seals like the DBH 5686 are found in gearboxes, pumps, electric motors, transmission shafts, and general industrial equipment. They keep lubricant inside the mechanism and prevent dust, water, or particles from entering, which can accelerate wear on bearings and gears. In process plants, factories, and maintenance operations, it is a common replacement part, changed when a leak appears or during scheduled inspections.

When installing this seal, ensure the shaft and housing are clean, free of burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment, then press evenly on the outer ring, never on the lip. The 11.11 mm width and the 31.75 mm and 53.97 mm diameters must match the cavity and shaft; if wear is present, measure and evaluate a repair. The Mz design defines the sealing type, so confirm it suits your speed and fluid.

If you need an equivalent to the DBH 5686, send us the code 5686 along with the shaft, housing, and width dimensions from the nameplate or drawing. You can also send a photo of the old seal and the operating conditions: lubricant type, temperature, and speed. With that data, MR Industrial Accessories compares alternatives within the DBH line and confirms the best fit for your assembly.
