The DBH 9291 is a radial shaft seal with an A 179 profile, sized for a 56 mm shaft and a 74.2 mm housing bore, with a height of 8.00/10.70 mm. It keeps lubricant in and contaminants out of rotating equipment, protecting bearings and bushings from premature wear. Common in gearboxes, pumps and transmission assemblies, it is available from MR Industrial Accessories as a supplied brand.

This seal carries the designation 9291 and the DBH series. The dimensions are shaft 56 mm, housing 74.2 mm and height 8.00/10.70 mm. The A 179 design indicates a sealing lip with a reinforced outer case, intended for press-fitting into a machined cavity. The dual height value means the seal can accommodate seat depth variations or combine a main lip with a dust guard, depending on the assembly. Before installation, inspect the housing for burrs or scratches that could harm the new lip.

Typical uses for a seal of this size include gearbox output shafts, centrifugal pumps, electric motors, conveyor rollers and chain- or belt-driven transmission equipment. In each case, the seal runs against a rotating shaft and stays in constant contact with oil or grease. It also appears in industrial washing machines, mixers and machine tools where coolant or fine chips are present. In high-vibration or high-temperature service, check the shaft condition before fitting the seal.

When selecting a radial shaft seal, confirm three things: shaft diameter and housing diameter match, height fits the cavity depth, and the lip material withstands the fluid and operating temperature. The A 179 design defines the mounting profile, so do not substitute another design without verifying cavity compatibility. During installation, lubricate the lip with the same oil used in the equipment, insert the seal perpendicular, and use a tube or press that applies force on the outer edge, never on the lip.

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