The DBH 5811 is a radial shaft seal that presses into the housing and runs against the rotating shaft to keep lubricant in and contaminants out. With an Mz design, it combines a metal case and a sealing lip, making it suitable for medium-section shafts in gearboxes, pumps, motors and transmissions.

This seal carries the designation 5811 and an Mz configuration. Its dimensions are shaft 57.15 mm, housing 79.38 mm and height 11.90 mm. The Mz design features a metal body and a single sealing lip, intended for rotating shafts lubricated with grease or oil. It is installed by pressing it into the housing bore, with the lip in contact with the shaft surface.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. Its role is to retain lubricant within the assembly and block dust, water and particles from entering. It also appears in machine tools and continuous process machinery, where lubricant loss or contamination can accelerate wear on bearings and gears.

Selecting the right seal starts with confirming the shaft diameter, housing bore and height. Also consider the lubricant type, shaft speed and operating temperature. During installation, clean the housing, lubricate the lip and use a proper driver to avoid damaging the seal. If the shaft is worn or rough, evaluate a seal with an auxiliary lip or a wear sleeve.

For an equivalent to the DBH 5811, send the code, the shaft, housing and height dimensions, and a photo of the original seal. With that information, we can identify a matching reference from our seals and oil seals line and advise on the most suitable design for your application and lubricant.
