The DBH 9291 seal is a radial shaft seal with an A 179 design that fits a 56 mm shaft and a 74.2 mm housing diameter, with a height of 8.00/10.70 mm. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a common replacement part in gearboxes, pumps and transmission equipment operating with rotating shafts. MR Accesorios Industriales supplies it as an official brand.

This item is a DBH radial shaft seal identified with the designation 9291. Its dimensions are: shaft diameter 56 mm, housing diameter 74.2 mm and height 8.00/10.70 mm. The A 179 design corresponds to a profile with a sealing lip and a reinforced body, designed to be press-fitted into a machined cavity. The double height indicates that the part allows variation in the seat or that it combines a main lip with a dust guard, depending on how the assembly is configured. Before replacing, check that the housing has no burrs or marks that could damage the new lip.

Typical applications for a seal of this size appear in gearboxes with output shafts, centrifugal pumps, electric motors, conveyor rollers and chain- or belt-driven transmission equipment. In all these cases the seal works against a rotating shaft and withstands continuous contact with oil or grease. It is also used in industrial washing machines, mixers and machine tools where coolant or fine chips are present. If the equipment operates with high vibration or elevated temperature, it is advisable to check the condition of the shaft before installing the seal.

To correctly select a radial shaft seal, take three points into account: that the shaft and housing diameters match those in the record, that the height is compatible with the cavity depth and that the lip material resists the fluid and working temperature. The A 179 design defines the mounting profile, so do not replace it with another design without confirming that the cavity accepts it. During installation, lubricate the lip with the same oil as the equipment, insert it perpendicular and use a tube or press that bears on the outer edge, never on the lip.
