The DBH 5311 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 designation indicates 20.00 mm shaft, 42.00 mm housing and 10.00 mm height, with Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings must be protected and lubrication kept in place.

This item is a DBH 5311 radial shaft seal, identified by its part number 5311 and by the dimensions listed on its product page: 20.00 mm shaft diameter (d), 42.00 mm housing diameter (D) and 10.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and metal body, intended to be press-fitted into the housing and to work on a rotating shaft. It is a standard replacement part within the radial shaft seal and seal category, and its function is to contain lubricant and prevent external contamination.

Typical applications for a seal of these dimensions appear in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also found in machine tools, conveyors and process equipment where a shaft rotates inside a housing and a reliable sealing barrier is needed. In all cases, the seal protects the bearings and the lubricant from the working environment and reduces losses from leaks.

To correctly select and install a seal such as the DBH 5311, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The shaft surface must be clean, free of burrs and deep marks, and it is advisable to lubricate the lip before installing it. The seal is inserted perpendicular to the shaft, with a suitable tool, avoiding blows that deform the metal body. If the shaft shows wear, consider a seal with the lip in another position.

If you need a seal equivalent to the DBH 5311, the most practical thing is to send us the full part number, the shaft, housing and height dimensions, and a photo or sample of the old seal.
