The DBH 8291 is a radial shaft seal that keeps oil or grease contained on rotating shaft equipment while blocking dust and water from the outside. It presses into the housing and its flexible lip rides on the shaft. As a wear part, it is replaced when leakage appears. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.
This seal carries the designation DBH 8291 and the Mx-R design, which defines the lip construction and case style. Its dimensions are shaft 38 mm, housing 73.95 mm, and height 11.00 mm. Those three measurements plus the design identify the seal unambiguously. If your equipment uses this size, the 8291 is the direct replacement.
Seals in this size range appear in gearboxes, pumps, electric motors, rollers, and power transmission equipment. They are also found in agricultural and road machinery and in process lines where lubricant must stay in and the bearing must stay protected. In every case the job is the same: separate the lubricated side from the exposed side and help extend the life of the bearing or bushing behind the seal.
Before installing a seal, inspect the shaft and housing. The shaft should have no burrs, deep scratches, or wear in the lip contact area, and the housing must be clean and free of deformation. Insert the seal perpendicular, using a tube or shim that presses on the metal edge, never on the lip. Lubricate the lip with the same grease or oil used in the equipment and confirm the internal spring is on the correct side.
To quote part number 8291, send the dimensions of the old seal—shaft diameter, housing diameter, and height—along with a photo of the part. With that information we can look for an equivalent in the same brand or another with similar performance. We can also advise you if the Mx-R design is not the right match for your application and a different lip or case geometry is needed.
