The DBH 6231 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its 6231 designation corresponds to a compact size of 15 mm shaft, 30 mm housing and 4.50 mm height, with Lx design. It is used in pumps, electric motors, gearboxes and power transmission equipment where axial space is limited and a reliable seal is required.

This item is a DBH 6231 radial shaft seal with the following dimensions: shaft diameter 15 mm, housing diameter 30 mm and height 4.50 mm. The Lx design indicates a single-lip configuration with spring, intended for rotating shafts with lubrication. The lip elastomer runs on a sliding surface that must be ground and free of marks. It is a wear component that is replaced during scheduled maintenance or when oil leakage appears.

Typical applications for this seal include small centrifugal pumps, low-power electric motors, speed reducers, gearboxes, compressors and belt or chain drive equipment. It is also found in machine tools, washing equipment and irrigation systems. In all cases, its function is to keep lubricant inside the assembly and prevent external agents from contaminating nearby bearings or gears.

To install the seal, verify that the shaft measures 15 mm and has a suitable surface roughness, with no burrs or splines that could damage the lip. The 30 mm housing must be clean and free of deformation. The 4.50 mm height defines the available axial space. Lubricate the lip before inserting it and use an installation tube that presses on the outer diameter, never on the lip. Avoid striking the seal and make sure it sits perpendicular to the shaft.
