Its dimensions are 25.40 mm for the shaft, 31.75 mm for the housing bore, and 3.20 mm in height.

This seal is commonly found in crankcases, covers, and flanges where axial space is tight. MR Industrial Accessories supplies this brand to help you match the exact size for your repair.

The DBH 5671 is part of the DBH line of radial shaft seals. It is identified by part number 5671. The designation indicates a shaft diameter of 25.40 mm, a housing bore of 31.75 mm, and a height of 3.20 mm. The Mt design refers to a seal with a single sealing lip and a metal body, intended for low-pressure applications. It works by pressing into the housing and sealing against the rotating shaft to keep lubricant in and contaminants out.

Seals like this one are used in gearboxes, electric motors, pumps, compressors, and other power transmission equipment. They also appear in spindles, rollers, and machine tool shafts where bearings need protection from dust or moisture. Because of its low height, the 5671 fits into thin covers or spaces where a wider seal would not.

Proper installation helps ensure a good seal. Clean the shaft and housing, remove any burrs or scratches, and lubricate the lip before pressing the seal into place. Make sure it sits square and avoid damaging the lip during installation. If the shaft is worn, a seal with the lip in a different position may work better. Selection also depends on speed, temperature, and the lubricant used, so check those details against the manufacturer's data.

If you need an alternative, provide part number 5671 or the shaft, housing, and height dimensions. We can search for equivalents in the same DBH line or in other brands we carry. We can also help determine if the Mt design is appropriate for your application or if a different lip type or material is needed.
