This item is a radial shaft seal from the DBH brand, identified with the code 5678. Its dimensions are 28.6 mm shaft diameter (d), 52.37 mm housing bore (D) and 11.11 mm height (h). The Mz design corresponds to a configuration with sealing lip and spring, intended for applications where the shaft rotates and lubricant must be contained. The 5678 designation allows it to be quickly located in catalogs and ordering systems. It is a common replacement part in industrial maintenance.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In all cases, its function is to prevent oil or grease leaks and protect bearings from the ingress of dust, water or particles. Due to its dimensions, it is common in medium-sized equipment, where radial space is limited and efficient sealing is required. It is also used in machine tools and hydraulic systems that operate with rotating shafts.

To correctly install this seal, verify that the shaft has the indicated dimension and a polished surface, free of burrs or marks that could damage the lip. The housing must be clean and have the specified diameter. Lubricate the lip before inserting it and install the seal with a press or suitable tool, avoiding direct blows. It is important to orient the lip toward the side of the fluid to be retained. If the equipment operates at high peripheral speed, consult the manufacturer's recommendations to select the lip material.
