The DBH 6817 is a radial shaft seal built to hold lubricant in and keep contaminants out of rotating assemblies. Its single lip runs with a spring and a metal outer case, and it presses into the housing bore. Shaft 44.50 mm, housing 57.15 mm, width 6.35 mm — a compact envelope for tight axial spaces. Treat it as a wear item: once it starts weeping, replace it.

The designation 6817 identifies this seal within the DBH line. The three figures to verify before ordering are the shaft diameter (d) at 44.50 mm, the housing bore (D) at 57.15 mm and the overall height (h) at 6.35 mm. The Mz construction means a sealing lip with a metal spring plus a metal outer case, made to be press-fitted into a cylindrical bore. DBH is a brand MR supplies, so the replacement keeps the same geometry and material for demanding industrial duty.

You will find seals of this series on gearboxes, pumps, electric motors, transmission shafts and process equipment. Two jobs matter here: keeping oil or grease where it belongs, and blocking dust, water and particles that shorten bearing and gear life. In food, chemical or water treatment operations, choosing the right lip and material is what determines how long the equipment runs between maintenance stops.

Before fitting a DBH 6817, inspect the shaft for burrs, splines or wear beyond 0.1 mm across the contact band. Coat the lip with the same oil the equipment uses, then push on the outer ring with even pressure — never on the lip itself. The bore has to be clean and free of dents. A deeply grooved shaft is a candidate for a wear sleeve to bring sealing back.

Looking for an equivalent? Send the code 6817 with the shaft, housing and height measurements, plus the equipment brand. A photo of the old seal or the housing drawing works too. We cross-reference the designation against the available options and confirm which one fits your application.
