The DBH 9178Pol radial shaft seal is a lip seal mounted in a machine's housing to retain lubricant and stop the ingress of dust, water or particles. With a 155 mm shaft diameter, 180 mm housing bore and 15 mm height, it covers large shafts in equipment where oil or grease must not escape. MR Accesorios Industriales carries it as part of its line of seals and oil seals.
This item is a radial shaft seal from the DBH line, identified by the code 9178Pol. Its dimensions are 155 mm shaft diameter (d), 180 mm housing bore diameter (D) and 15.00 mm height (h). The Mx-R-AH design corresponds to a seal with a sealing lip and radial mounting configuration, intended for machined housings. The lip elastomer and the internal spring work against the rotating shaft to maintain sealing.
It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where the shaft rotates inside a fixed housing. It is commonly found in continuous-process machinery, since the seal protects the bearings and prevents lubricant from leaking to the outside. It is also used in applications with moderate exposure to dust or splashes, where the auxiliary lip helps contain contamination.
To select it, verify that the shaft and housing bore diameters match the values on the data sheet and that the 15.00 mm height fits the cavity. The shaft must be ground, free of burrs or marks, with a roughness suitable to avoid damaging the lip. Lubricate the seal before mounting it, insert it perpendicular to the shaft and avoid striking it unevenly. If the equipment runs at high speed or temperature, check the material's compatibility.
If you need a close size or an equivalent from another brand, send us the code 9178Pol along with the shaft, housing bore and height dimensions. You can also send a photo of the old seal or the drawing of the cavity. With that data we review the DBH line and the available alternatives so that the replacement fits without modifications. If the Mx-R-AH design is not the right one, we will guide you toward the appropriate variant.
