The DBH 6251 is a radial shaft seal of the single-lip, spring-loaded type. It keeps lubricant in and contaminants out on rotating shafts. The size is compact: shaft 19 mm, housing bore 27 mm, height 6.00 mm. You will find it in small pumps, low-power electric motors, gearboxes and similar power transmission equipment. MR Industrial Accessories supplies this brand and helps you verify the size before you request a quote.

This seal follows the Ls design: one sealing lip with a spring, a metal case and an outer elastomer layer. The lip presses lightly against the shaft, and the spring keeps that contact as the lip wears. The 19 mm shaft, 27 mm housing and 6.00 mm height make it a good fit where axial space is tight and you need dependable sealing against oil or grease.

Typical uses include small centrifugal pumps, low-power motors, gearboxes, compressors, fans and other power transmission equipment. It also shows up in agricultural machinery, power tools and process equipment. The job is always the same: separate the lubricated side from the outside, stop lubricant loss and keep dust, water or particles away from bearings and bushings.

Installation starts with a clean shaft, free of burrs and marks, and a fine finish where the lip runs. Lubricate the lip before pressing it in, and use a flat driver so it seats straight without deforming. The housing must be in good shape and deep enough for the seal to sit correctly. If the shaft is worn, a seal with the lip in a different position may be an option. Speed, temperature and lubricant type all matter when selecting a replacement.

If you cannot find the 6251 or need an equivalent size, send the code, the shaft, housing and height dimensions, and a photo of the old seal if you have one. With that information we look for an alternative in the DBH line or in other brands we carry. We can also help when the original seal has no readable identification and the size has to be determined by measurement.
