The DBH 6736 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its Mz-R profile combines a metal case with an elastomeric sealing lip. The size designation reads as a 17 mm shaft, a 28 mm housing bore and a 7.00/10.00 mm height, the taller figure covering a stepped or deeper cavity. Treat it as a wear item: once the elastomer hardens or oil starts to weep past the lip, replacement is due.

Reading the code helps when you are matching a seal already in service. DBH is the brand line, 6736 is the item reference, and Mz-R describes the construction: an outer metal body with a sealing lip molded to it. The 7.00/10.00 mm height tells you the profile can sit in a cavity of more than one depth, either because the housing is stepped or because the seal can be positioned at two levels. For the exact geometry, compare the part against the manufacturer's data sheet before ordering.

You will find this type of seal on gearboxes, pumps, electric motors, line shafts and process machinery. It does two jobs at once: holding oil or grease around the bearing and blocking dust, washdown water and chips from reaching it. Where contamination is heavy, the choice of elastomer and the internal spring design matter as much as the dimensions. The compact 17 x 28 mm footprint puts this seal in low and medium power equipment.

Installation decides how long the seal lasts. Check the shaft for burrs, scratches or a worn contact band, polish it if needed, and lubricate the surface before sliding the seal on. The bore must be clean and round. Drive the seal in with a tube that presses on the outer case, never on the lip. If the shaft already shows a groove, a wear sleeve or a seal with an auxiliary lip is worth considering. The 7.00/10.00 mm height gives some room during fitting, but follow the position the equipment maker specifies.
