The DBH 9159 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the ingress of dust, water or particles. Its designation 9159 corresponds to a standard size of 40.00 mm shaft diameter, 85.00 mm housing bore diameter and 10.00 mm height, in the Lx design. It is used in gearboxes, pumps, electric motors and transmission equipment where bearings must be protected and leaks prevented.

This item is a radial shaft seal from the DBH line, identified by part number 9159. According to the product page data, it has a shaft diameter (d) of 40 mm, a housing bore diameter (D) of 85 mm and a height (h) of 10.00 mm. The Lx design indicates a single-lip configuration with a spring, suitable for rotating shafts with lubrication. The elastomeric lip runs on the shaft surface and the metal case is press-fitted into the housing. It is a wear part that should be replaced when lubricant leakage or contaminant ingress appears.

Typical applications for an oil seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt- or chain-driven transmission equipment. In all cases it seals the passage of the shaft through the housing, retaining the oil or grease and preventing dirt and moisture from entering. It is also found in machine tools, conveyors and agricultural or road equipment where there are rotating shafts with bearings that must remain lubricated.

To install a radial shaft seal, check that the shaft has no burrs, deep scratches or wear in the lip contact area. The shaft surface must be clean and lubricated before inserting the seal. The housing must be machined with the appropriate tolerance and without steps that deform the case. It is recommended to use a tube or socket with an outer diameter similar to that of the seal to tap only on the metal ring, never on the lip. If the shaft has a groove or marked wear, it may be necessary to replace the shaft or use a seal with the lip in a different position.
