The DBH 9291 oil 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 that operate with rotating shafts. MR Accesorios Industriales supplies it as a 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 for 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 an oil 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 those cases the oil 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 a lot of vibration or high temperature, it is best to check the condition of the shaft before fitting the seal.

To select a radial shaft seal correctly, keep three points in mind: that the shaft diameter and the housing diameter match, that the height is compatible with the depth of the cavity, and that the lip material resists the fluid and the 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 used in the equipment, insert it perpendicular and use a tube or press that bears on the outer edge, never on the lip.

To quote the code 9291, send us the shaft, housing and height dimensions shown on the nameplate or on the equipment drawing. With that data we can look for an alternative within the same radial shaft seal category. If the housing is worn, we evaluate repair options or a seal with a sleeve. The more complete the information you send, the faster we can confirm the right part.
