The DBH 8291 radial shaft seal is a lip seal that closes off the passage of oil or grease in equipment with a rotating shaft, while also preventing dust and water from entering from the outside. It is press-fitted into the housing and runs on the shaft with a flexible lip. It is a wear part: when it starts to leak, it is replaced. MR Accesorios Industriales carries this official brand and advises you on choosing the correct seal.

This item is a DBH 8291 radial shaft seal with the following dimensions: shaft diameter 38 mm, housing diameter 73.95 mm and height 11.00 mm. The indicated design is Mx-R, which corresponds to the lip construction and the type of case. With those three data points — shaft, housing and height — plus the design, the seal is identified without ambiguity. If your equipment uses this size, the 8291 is the direct replacement.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, rollers and power transmission equipment. They also appear in agricultural and road machinery and in process lines where lubricant must be retained and the bearing protected from the environment. In all those cases they perform the same function: separating the lubricated side from the exposed side and extending the life of the bearing or bushing behind them.

To install a seal, the condition of the shaft and the housing must be checked. The shaft must not have burrs, deep scratches or wear in the lip contact area, and the housing must be clean and free of deformation. The seal is inserted perpendicular, with a tube or shim that presses on the metal edge, never on the lip. Before fitting it, lubricate the lip with the same grease or oil used in the equipment and check that the internal spring is on the correct side.

If you cannot find part number 8291 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part. With that we look for the equivalent in the same brand or in another with similar performance. We can also advise you if the Mx-R design is not the one that corresponds to your application and a different lip or case geometry is needed.
