The DBH 5803 radial shaft seal is a lip seal mounted in a machine housing to retain lubricant and block the entry of dust, water or particles. Its Mz design combines a sealing lip with a metal body that fits under pressure into the cavity. It is used in gearboxes, pumps, electric motors and power transmission equipment, where the shaft rotates continuously and a reliable barrier is needed between the inside and the outside.

The DBH 5803 is identified by its designation and by the dimensions shown in the data sheet: shaft diameter of 44.45 mm, housing diameter of 70.05 mm and height of 12.70 mm. The Mz design corresponds to a seal with a sealing lip and metal reinforcement, designed to be press-fitted into the housing. These values are what you must verify against the shaft and the cavity before ordering, because any difference in diameter or height changes the fit and the sealing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. In all cases it serves to retain oil or grease inside the assembly and prevent contaminants from entering from the outside. It is a wear part: over time the lip hardens or wears, and a lubricant leak appears that should be corrected before it affects bearings or gears.

To select the seal, compare the shaft diameter, housing diameter and height with the values in the data sheet. The Mz design defines the type of lip and reinforcement, so if the original has a different geometry, it is advisable to confirm the equivalence. During installation, lubricate the lip before sliding it onto the shaft, check that it is not twisted and make sure the housing is clean and free of burrs. Incorrect installation is the most common cause of premature leaks.

If you need a seal with nearby dimensions or an equivalent from another brand, send us the original code, the shaft diameter, the housing diameter and the height. With that data we will look for the closest option within the DBH line or from other brands we supply. We can also advise you if the Mz design does not match the one installed on your equipment and a variant with a different type of lip or reinforcement needs to be evaluated.
