The DBH 5311 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its designation indicates a 20.00 mm shaft, 42.00 mm housing and 10.00 mm height, with an Lx design. It is used in gearboxes, pumps, electric motors and power transmission equipment where bearings must be protected and lubrication kept at the exact point.

This item is a DBH 5311 radial shaft seal, identified by its code 5311 and by the dimensions shown 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 case, designed to be press-fitted into the housing and run against a rotating shaft. It is a standard replacement part within the radial seals and oil seals category, and its function is to contain lubricant and prevent external contamination.

Typical applications for a seal of these dimensions are found 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 required. In all cases, the seal protects the bearings and the lubricant from the working environment and reduces leakage losses.

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 installation. The seal is inserted perpendicular to the shaft, with a suitable tool, avoiding blows that deform the metal case. If the shaft shows wear, consider a neighboring size or a seal with the lip in a different position.

If you need a seal equivalent to the DBH 5311 or a nearby size, the most practical approach is to send us the full code, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can compare against the available alternatives and confirm the option that best suits your equipment. We can also help you if the original seal has no visible brand or if you need an intermediate size within the same category.
