The DBH 5923 is a radial shaft seal sized for a 145 mm shaft, a 170 mm housing bore and a 12 mm height. Its Lx configuration uses a main sealing lip plus a secondary exclusion lip, which helps keep dust and other contaminants away from the sealing zone. This makes it a practical choice for rotating shafts where lubricant retention and particle exclusion both matter. MR Industrial Accessories LLC supplies this seal to maintenance and purchasing teams across the United States and Latin America.
Reading the code is straightforward: 145 mm is the shaft diameter (d), 170 mm is the housing diameter (D) and 12 mm is the height (h). The Lx designation points to a lip arrangement with a secondary exclusion lip in addition to the primary sealing lip. Keep in mind that this is a rotary shaft seal, so it is not intended for reciprocating motion or for high-pressure service.
You will typically find this size in gearboxes, pumps, reducers, rollers and other power transmission equipment. It works by holding lubricant inside the assembly while blocking external particles from reaching bearings or gears. Before ordering, confirm the actual shaft and housing dimensions, since nominal sizes can vary slightly in worn equipment.
Installation calls for a clean shaft and bore, free of burrs, nicks or scratches. Coat the lip with the same oil or grease used in the machine, then press the seal in squarely using a proper driver or tube — never strike the lip directly. When selecting a replacement, account for shaft speed, operating temperature and how the elastomer reacts to the fluid being sealed.
If you need an alternative to the DBH 5923, send the part number or your measured dimensions and the team can suggest equivalent options in other configurations. The three critical dimensions to match are shaft diameter, housing diameter and height. Advice on lip type and material is available based on your application conditions.
