The DBH 8198 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 28.46 mm shaft, 36.50 mm housing bore and 5.50 mm height, it is used in equipment where axial space is limited. It is a wear part that should be replaced when there are signs of leakage or hardening of the elastomer.

This DBH 8198 seal has an Ls design and is identified by its dimensions: shaft diameter 28.46 mm, housing bore diameter 36.50 mm and height 5.50 mm. The sealing lip runs on the rotating shaft, while the outer diameter fits into the housing to ensure tightness. The designation 8198 corresponds to the manufacturer's code and allows the exact part to be located. It is a standard component within the DBH radial shaft seal line that MR supplies.

Typical applications include gearboxes, pumps, electric motors, transmission shafts and power transmission equipment in general. It is also found in agricultural machinery, process equipment and lubrication systems where oil or grease must be contained. Its compact size makes it suitable for assemblies with little axial space, such as medium-section bearings or split plummer block housings. In all cases, selection depends on speed, temperature and type of lubricant.

For installation, verify that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip before inserting it and avoid striking it during placement. Shaft eccentricity and axial play must be within the limits recommended by the manufacturer. If the previous seal failed, check the shaft surface: excessive wear accelerates failure of the new seal. Correct alignment extends the service life of the component.
