The DBH 9178Pol radial shaft seal is a lip seal mounted in a machine housing to retain lubricant and stop the entry 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 sells 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 a radial mounting configuration, intended for machined housings. The elastomer of the lip and the internal spring work on 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 diameters match the values on the data sheet and that the 15.00 mm height fits into the cavity. The shaft must be ground, free of burrs or marks, with a suitable surface roughness so as not to damage the lip. Lubricate the seal before mounting it, insert it perpendicular to the shaft and avoid hitting it unevenly. If the equipment operates at high speed or temperature, check the material compatibility.

To quote the code 9178Pol, send us the shaft, housing 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 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.
