The DBH 8991 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 90 mm shaft diameter, 130 mm housing diameter and 12 mm height place it in medium and large equipment. It is press-fitted into the housing and runs against the shaft, with the lip resting on the running surface. It is a wear part: when oil leakage or dust ingress appears, it is replaced. MR Accesorios Industriales supplies it as part of its seals line.

This item is a radial shaft seal from the DBH brand, identified with part number 8991. Its dimensions are 90 mm shaft diameter (d), 130 mm housing diameter (D) and 12.00 mm height (h). The indicated design is Lx, which corresponds to a seal with a sealing lip and standard configuration for rotating shafts. The 8991 designation makes it quick to locate in the catalogue and cross-check against the size you need. If your equipment calls for a 90 x 130 x 12 seal, this is the part number to check.

It is used in gearboxes, pumps, electric motors, rollers and power transmission equipment where a shaft rotates inside a housing containing lubricant. It also appears in agricultural machinery, conveyors and process equipment. Its function is twofold: it keeps oil or grease in and blocks the ingress of dust, water or particles. In environments with heavy dirt or frequent washing, the seal works under demanding conditions and should be checked at every maintenance stop.

To install it, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting it and fit the seal perpendicular, without deforming it. If the shaft shows a marked wear groove, a wear sleeve may be needed or a seal with the lip in a different position may have to be considered. Selection depends on speed, temperature and lubricant type; with that data we confirm whether the Lx design is the right one.

If you cannot find part number 8991 or need a nearby size, send us the shaft diameter, housing diameter and height you measured. The code stamped on the old seal or a photo with the measurement also works. With that data we look for the equivalent in DBH or another brand in the line we supply. The designation does not have to match: what matters is the size and the lip type.

MR Accesorios Industriales supplies the DBH brand within its seals and oil seals line. If this seal is for your equipment, send part number 8991 by WhatsApp along with the measurement and we will send you the quote. We can also help you identify the replacement if the original is no longer available. More than 80 years supporting industry with technical support and spare parts.
