This item is a radial shaft seal from the DBH brand, identified by part number 5777. Its standard dimensions are 34.93 mm for the shaft diameter (d), 57.15 mm for the housing bore diameter (D) and 11.90 mm total height (h). The Mz design corresponds to a construction variant that defines the geometry of the lip and the metal case. These values come from the manufacturer's designation and must be checked against the original part before replacing it.

Radial shaft seals such as the DBH 5777 are used in gearboxes, pumps, electric motors, drive shafts and continuous process equipment. Their function is twofold: to retain the oil or grease inside the assembly and to prevent the ingress of dust, water or particles that accelerate wear on bearings and gears. In food, chemical or water treatment plants, the choice of lip material is critical depending on the fluid and the operating temperature.

To install this seal correctly, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip with the same oil used in the equipment before inserting it, and press perpendicularly so as not to damage the seal. Shaft runout and surface roughness affect service life: consult the permissible values according to the manufacturer. If the shaft is worn, consider a repair sleeve or an alternative size.
