The DBH 8363 is a radial shaft seal that fits a 86 mm shaft, a 121 mm housing and a 13.00 mm height. It keeps oil or grease where it belongs and blocks dust, water and particles from reaching bearings and gears. As a wear part, it is normally renewed whenever the assembly is opened.

This lip seal comes from the DBH brand and carries the code 8363. The Lx design means a sealing lip on a metal body, made to be press-fitted into a cylindrical housing. The size reads as shaft 86 mm, housing 121 mm, height 13.00 mm, so it is easy to match against the old seal or the equipment drawing. MR Industrial Accessories supplies this brand within its seals and oil seals range.

You will find this seal in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. It works on medium-diameter shafts, which are common in industrial machinery, process lines and motion systems, and it also appears in automotive and agricultural machinery that runs continuously.

Before ordering, confirm the three dimensions against the housing and shaft. The shaft surface should be smooth, with no burrs, scratches or heavy wear, or the lip cannot seal. Lubricate the lip with the same oil or grease used in the equipment and press the seal in squarely. If the shaft has a worn track, you can offset the seal slightly or fit a repair sleeve.
