This item is a DBH radial shaft seal, identified by part number 6519. Its dimensions are 74 mm shaft diameter, 116 mm housing diameter and 20.00 mm height. The A 108 design corresponds to a specific manufacturer's construction, which defines the lip profile and the type of case. It is a replacement part for shafts that rotate inside a cylindrical housing and need to retain oil or grease while preventing the entry of dust, water or particles. It is press-fitted into the housing and its lip runs on the shaft.

Typical applications for a seal of these dimensions are found in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It is also found in agricultural, road and continuous process machinery, where the shaft rotates at moderate speeds and lubricant is present. In all cases it performs the dynamic sealing function: it separates the lubricated interior from the outside environment and extends the life of bearings and gears by preventing lubricant loss and the entry of contaminants.

To select and install it correctly, check that the shaft diameter, housing diameter and height match the values on the product page. The shaft must be clean, free of burrs or deep marks in the lip contact area, and the housing must have the appropriate finish and tolerance. Lubricate the lip before installation and use a tool that prevents damage. Speed, temperature and the type of fluid determine the choice of lip material; if your application is demanding, contact us and we will advise you.
