The DBH 9937 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the ingress of dust and water in rotating equipment. It mounts between a rotating shaft and a fixed housing, and works supported on the shaft by an elastomeric lip. Its A 094 design corresponds to a standard seal construction with metal reinforcement and single lip. It is a wear part: when lubricant loss or contaminant ingress appears, it is replaced. MR Accesorios Industriales carries this brand and advises you to choose the correct size.

This item is a DBH radial shaft seal with designation 9937. Its dimensions are: shaft diameter 117.5 mm, housing diameter 154 mm and total height 14.5/16.5 mm. The indicated design is A 094, which defines the geometry of the lip and the metal body. The height is expressed as a range because the lip can flex or seat with a slight axial variation depending on the mounting. Always verify these dimensions against the housing and shaft before ordering.

Radial shaft seals of this type are used in gearboxes, pumps, electric motors, rollers, mixers and transmission equipment. Their function is to retain the lubricant inside the assembly and prevent particles, water or steam from entering. In environments with dust, chips or frequent washing, the seal works as the main barrier. They are also used on fan, agitator and conveyor shafts, where speed and temperature are moderate. If the equipment operates with a lot of vibration or misalignment, it is advisable to check the condition of the shaft and housing.

To mount a seal, clean the shaft and housing, remove burrs and verify there are no marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it. Place it perpendicular to the shaft and push it with a tube or shim that rests on the outer ring, never on the lip. If the housing has a step or chamfer, respect the seating depth. When selecting, take into account the peripheral speed, working temperature and the type of fluid to be retained.

If you cannot find the code 9937 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. The code engraved on the seal or the equipment brand also helps. With that data we look for an equivalent in the same brand or in another line we carry. If the shaft is worn, we evaluate options with a more robust lip or with a wear sleeve. The idea is that the equipment does not stop for a wear part.
