The DBH 9908 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the ingress of dust, water or particles. Its A 308-R H design combines a sealing lip with a metal body that gives it rigidity and facilitates press fitting. It is used in gearboxes, pumps, electric motors and transmission equipment where there is continuous rotation and a need to protect the bearings.

This seal has a shaft diameter of 35 mm, a housing bore diameter of 62 mm and a height of 8.00/11.30 mm. That variable height corresponds to a profile with an outer lip that may sit flush or protrude slightly depending on the cavity design. The A 308-R H design indicates a configuration with a sealing lip and metal reinforcement, suitable for rotating shafts with permanent lubrication. The DBH brand is a brand that MR carries, with standardized dimensions for replacement.

Typical applications for this seal are gearboxes, speed reducers, centrifugal pumps, electric motors and belt or chain transmission equipment. It is also found in machine tools, compressors and conveying systems where oil leaks and lubricant contamination must be avoided. In all those cases it works on a 35 mm shaft and inside a 62 mm housing bore, with the 8.00/11.30 mm height as a reference for the cavity.

To install it, check that the shaft has no burrs or wear and that the housing bore is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a flat tool so as not to damage the seal. Seal selection depends on shaft speed, operating temperature and the type of lubricant; if those data are not on the data sheet, it is best to confirm them with the manufacturer before replacing.

To quote an equivalent, send us the code 9908 or the dimensions 35 x 62 x 8.00/11.30 mm and the A 308-R H design. With those data we can look for an alternative within the same category of radial shaft seals or check the manufacturer's data sheet to confirm compatibility. We can also advise you if the housing bore has a different depth or if the shaft shows wear that requires a special size.
