The DBH 5804 is a radial shaft seal that keeps oil or grease in and contaminants out of assemblies with a rotating shaft. You will find it in gearboxes, pumps, motors and transmissions. Its code 5804 covers a 30 mm shaft, a 72 mm housing bore and a 10 mm height, in the Mz design. MR Industrial Accessories helps you confirm the right seal for the application.

This is a single-lip radial shaft seal with a metal body. The Mz designation refers to the manufacturer's construction layout for this size. Read the three dimensions in order: shaft 30 mm, housing 72 mm, height 10 mm. Check each one against the shaft and the cavity before installation.

Common uses include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case the seal retains lubricant inside the assembly and blocks dust or water from entering, which would otherwise speed up wear on bearings and gears. Treat it as a wear part and replace it when leaks or unusual noise appear.

When selecting a seal, match the shaft diameter, housing diameter and available height first. Then consider rotation speed, working temperature and the lubricant type. The Mz design of the DBH 5804 suits oil or grease lubrication under moderate operating conditions. If the shaft is worn, look at options such as an offset lip seal or a repair sleeve.

Proper installation affects how the seal performs. Lubricate the lip before mounting, confirm the shaft has no burrs or marks, and make sure the housing is clean and undistorted.
