The DBH 6731Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 120 mm shaft, a 145 mm housing bore and a 15 mm width, and its Kx profile is suited to assemblies with limited axial room. You will find this seal in pumps, motors and gearboxes, among other machines. MR Industrial Accessories supplies it and can quote it on request.

This seal's dimensions are shaft 120 mm, housing 145 mm and width 15.00 mm. The Kx designation points to a sealing lip plus a secondary exclusion lip. Within the DBH line, 6731Pol is the code that defines both the size and the construction type. It is a radial seal for rotating shafts, not for linear movement or for high-pressure service. It presses into the housing and runs against the shaft surface.

Seals of this size are common in centrifugal pumps, medium electric motors, reducers and gearboxes, and power transmission equipment in general. In those assemblies they stop oil or grease from escaping and keep dust and particles away from the bearings. You will also see them in agricultural machinery, process equipment and pumping systems where the shaft turns at moderate speed and the working temperature matches a standard industrial lubricant.

To choose the right seal, confirm that the shaft and housing dimensions match the equipment. The shaft surface should be ground, without splines or wear, and the housing needs the correct diameter and depth. When installing, coat the lip with the same oil or grease used in the machine, press the seal in straight and do not strike the lip. If the shaft shows a groove or wear, a seal with the lip in a different position may be the better option.
