The DBH 6519 is a radial shaft seal built for rotating shafts, sized 74 mm at the bore, 116 mm at the outer case and 20 mm in height, in the A 108 design. Its job is to hold lubricant inside the housing and keep dust, water and particles out, which is why it shows up in gearboxes, pumps, motors and other power transmission equipment. MR supplies this brand and helps buyers match the right seal to the shaft and housing they are working on.

Reading the code helps when you are ordering. The 6519 is the part number, DBH identifies the seal family, and the three figures describe the fit: shaft 74 mm, housing 116 mm, width 20 mm. The A 108 designation refers to the manufacturer's construction, which sets the lip profile and how the case is made. A seal like this sits press-fitted in a cylindrical bore while its lip rides on the turning shaft.

These dimensions turn up in reducers, centrifugal pumps, electric motors, compressors and transmission assemblies, as well as in agricultural, road and process machinery where shafts rotate at moderate speed with lubricant present. The seal is what separates the lubricated side from the environment, and by holding oil or grease in place and blocking contaminants, it helps bearings and gears reach their expected service life.

Before installing, confirm shaft, bore and width against the values above. The shaft should be clean and free of burrs or deep scoring where the lip contacts it, and the housing needs the right finish and tolerance. Oil the lip before you seat the seal and use a driver that will not cut or distort it. Lip material is chosen based on speed, temperature and the fluid involved, so tell us about your application if conditions are severe.

If you want a different design or a comparable seal from another source, send the equipment details or caliper readings. With part number 6519 or the 74 x 116 x 20 dimensions we can search for the closest option, including variations in material or lip configuration to suit the fluid and operating temperature. The more information you provide, the more precise our suggestion will be.
