Part number DBH 5618 is a radial shaft seal from the DBH line carried by MR Industrial Accessories. It is an Lx type lip seal that sits in a housing bore and works against a rotating shaft, keeping lubricant inside the assembly and keeping dust, water and other particles out. The size is written as 25.40 mm shaft, 36.50 mm housing and 6.35 mm width, which makes it a common fit on pumps, motors, gear reducers and other transmission equipment handled in day-to-day plant maintenance.

Reading the reference is straightforward. The 5618 designation groups this seal with others of the same size family, while the numbers that matter on the bench are the three measurements: 25.40 mm at the shaft, 36.50 mm at the housing bore and 6.35 mm in width. Matching all three against the seal you are removing is the first check before ordering. DBH is one of the brands MR supplies, and the part is ordered by its part number together with those dimensions.

The Lx design describes a seal built with a metal outer case and a single sealing lip. That construction suits rotating shafts running with oil or grease, which is why seals in this format turn up in centrifugal pumps, electric motors, gearboxes, compressors, mixers and machine tools, as well as in agricultural implements and power transmission assemblies. Two jobs are done at once: the lip holds lubricant in, and the same lip keeps contaminants out. Letting grit reach the bearings or bushings is what shortens their service life.

Installation rewards a little care. Confirm the bore and shaft sizes first, then check that the shaft is clean and free of burrs, scoring or deep marks, and that the housing is not deformed. Lubricating the lip before it goes in helps it seat without damage, and the pressing force should go on the case, never on the lip itself. On a shaft that already shows wear, a seal with an auxiliary lip is worth considering.

When you need an equivalent, the fastest route is to send the complete seal part number, the shaft, housing and width measurements, and a photo of the part. With that information the team can locate the matching DBH designation in the same category and tell you whether a standardized replacement size should be evaluated instead.
