The DBH 6817 oil seal is a single-lip radial seal with a spring, designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 44.50 mm shaft diameter, 57.15 mm housing diameter and 6.35 mm height make it suitable for equipment where axial space is limited. It is press-fitted into the housing and runs on the shaft with an oil film that ensures sealing and low friction. It is a wear part that should be replaced at the first sign of leakage.

This item is a DBH 6817 radial shaft seal, identified by its designation 6817. Its standard dimensions are 44.50 mm shaft diameter (d), 57.15 mm housing diameter (D) and 6.35 mm overall height (h). The Mz design corresponds to a sealing lip with a metal spring and a metal outer case, intended for press fitting into a cylindrical housing. DBH is a brand MR sells, so the replacement part keeps the original geometry and material for demanding industrial applications.

Seals in this series are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to retain the oil or grease inside the assembly and to prevent the entry of dust, water or particles that accelerate wear on bearings and gears. In food, chemical or water treatment plants, the correct selection of the lip and seal material defines equipment service life and maintenance frequency.

To install a DBH 6817 oil seal, check that the shaft has no burrs, splines or wear greater than 0.1 mm in the contact area. Lubricate the lip with the same oil used in the equipment before inserting it, and apply uniform pressure on the outer ring, never on the lip. The housing must be clean and free of dents. If the shaft shows a deep groove, consider a wear sleeve to restore sealing.
