The DBH 9951/85 radial shaft seal is a lip seal mounted on a rotating shaft to retain lubricant inside the housing and keep out dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotating inside a housing must be sealed. Its A 100 design and dimensions of 18.80 mm shaft, 29.30 mm housing and 7.00 mm height make it suitable for compact spaces.

This DBH 9951/85 oil seal has a shaft diameter of 18.80 mm, a housing diameter of 29.30 mm and a height of 7.00 mm. The A 100 design corresponds to a single-lip seal with a metal case and sealing lip, intended for rotating shafts with lubrication. The 9951/85 designation identifies the exact size within the DBH line, so it is advisable to verify those three values before ordering: the shaft diameter governs the fit and the height governs the space available in the housing.

Typical applications for this type of oil seal are gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all these cases the seal works on a rotating shaft and separates the oil or grease from the outside environment. It is also used in machine tools, washing equipment and systems where there is splashing or dust. If the equipment operates with heavy vibration or temperature, it is advisable to check the lip material before replacing.

To install a radial shaft seal, the shaft must be clean, free of burrs and marks, and the housing free of deformation. It is recommended to lubricate the lip with the same grease or oil used in the equipment before inserting it, and to use an installation tube that presses on the metal edge, never on the lip. Selection depends on shaft speed, operating temperature and the type of fluid to be retained. If the original seal has a spring or an auxiliary lip, that configuration must be respected when ordering the replacement.
