The DBH 9724Pol is a radial shaft seal built for rotating shafts. Its Mx-Bidi configuration points to a double-lip, bidirectional layout, and the size callout reads 54 mm at the shaft, 73 mm at the housing bore and 11.00 mm in height. Seals in this family hold lubricant where it belongs and keep dust, water and other contaminants out of gearboxes, pumps and similar machinery. MR Industrial Accessories supplies this brand and can help you confirm the right seal for the job.

Reading the code and the size string is the quickest way to check a replacement. The 9724Pol is the DBH reference, while 54x73x11 follows the usual order: d for the shaft, D for the housing bore, h for the height. The Mx-Bidi designation tells you the lip arrangement works in both directions of rotation, which matters on reversing shafts or where pressure can alternate. The elastomer and the internal spring are what keep the lip in contact with the shaft.

You will run into this seal on gearboxes and reducers, centrifugal pumps, electric motors and power transmission equipment. In those spots its job is to stop oil or grease from escaping and to block dust, water or particles from reaching bearings and gears. Industrial machinery, process equipment and heavy vehicles are common hosts, since the operating conditions there call for sealing that holds up over time.

Installation decides how long the seal lasts. Clean the shaft and the housing bore and remove burrs or marks before you start. Put a light film of the same oil or grease used in the application on the lip, then press the seal in squarely with a mounting tube that bears on the outer diameter. Do not hit the lip or the spring. When you select the seal, weigh shaft speed, operating temperature and how the elastomer reacts to the fluid being retained.

If you are matching an existing seal, send the code 9724Pol or the dimensions 54x73x11 and we will look at alternatives in other brands or similar configurations, keeping the required tolerances and design in mind. We can also tell you whether your application calls for a seal with special characteristics, such as higher thermal or chemical resistance. MR Industrial Accessories stocks the DBH brand within its seals and oil seals line.
