The DBH 6251 oil seal is a single-lip radial shaft seal that mounts on rotating shafts to retain lubricant and block the entry of dust, water or particles. With a 19 mm shaft diameter, 27 mm housing bore and 6 mm height, it is a compact size found in pumps, small electric motors, gearboxes and light-duty power transmission equipment. MR Accesorios Industriales carries this brand and helps you confirm it is the right size before you request a quote.

The DBH 6251 is an Ls design oil seal: single sealing lip with spring, metal case and outer elastomer. Its dimensions are 19 mm shaft diameter (d), 27 mm housing bore diameter (D) and 6.00 mm height (h). That combination makes it suitable for housings where axial space is limited and a reliable seal against oil or grease leaks is required. The lip runs on the shaft with slight interference, and the internal spring maintains contact pressure as wear occurs.

It is used in applications with continuous rotation and the presence of lubricant: small centrifugal pumps, low-power electric motors, gearboxes, compressors, fans and power transmission equipment. It also appears in agricultural machinery, power tools and process equipment. In every case it performs the same function: separate the lubricated side from the environment, prevent losses and protect nearby bearings or bushings from external contamination.

To install it, check that the shaft is clean, free of burrs and marks, and that the surface where the lip runs has a fine finish. Lubricate the lip before inserting it and use a flat driver so as not to deform it. The housing must be in good condition and deep enough for the seal to seat straight. If the shaft shows wear, consider a nearby size or a seal with the lip in a different position. Selection depends on speed, temperature and lubricant type, data worth having on hand when you enquire.

If you cannot find the 6251 or need an equivalent size, send us the code, the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we look for the alternative within the DBH line or other brands we carry. We can also guide you if the original seal has no legible identification and the size has to be reconstructed by measurement.
