This item is a DBH 5686 radial shaft seal, identified by its designation 5686. Its nominal dimensions are 31.75 mm shaft diameter (d), 53.97 mm housing diameter (D) and 11.11 mm height (h). The Mz design corresponds to a configuration with sealing lip and metal body, suitable for retaining oil or grease on rotating shafts. It is a sealing component that works in direct contact with the shaft and the cavity, so its correct selection depends on the actual dimensions of the assembly.

Radial shaft seals such as the DBH 5686 are used in gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. Their function is to confine the lubricant inside the mechanism and block dust, water or particles that could accelerate wear of bearings and gears. In process plants, factories and machinery maintenance, it is a common replacement part that is replaced when a leak appears or when the equipment is disassembled for a scheduled inspection.

To install this seal, check that the shaft and housing are clean, free of burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it, and press evenly on the outer ring, never on the lip. The 11.11 mm height and the 31.75 and 53.97 mm diameters must match the cavity and shaft dimensions; if there is wear, it is advisable to measure and evaluate a repair. The Mz design defines the type of sealing, so confirm that it is suitable for the speed and fluid of your application.
