The DBH 8363 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that could damage bearings and gears. With dimensions of 86 mm shaft, 121 mm housing and 13 mm height, it is press-fitted into the housing and runs on the shaft surface. It is a wear part that should be replaced at every teardown to ensure the equipment's sealing.

This item is a radial shaft seal from the DBH brand, identified by code 8363. Its dimensions are 86 mm shaft diameter (d), 121 mm housing diameter (D) and 13.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and metal body, suitable for press fitting into a cylindrical housing. The 8363 designation makes it easy to locate in the catalogue and replace with an equivalent of similar characteristics. MR Accesorios Industriales carries this brand as part of its seals and oil seals line.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, it protects the bearings from contaminant ingress and prevents oil or grease leaks. Due to its size, it is used on medium-diameter shafts, common in industrial machinery, process equipment and motion systems. It can also be found in automotive and agricultural machinery applications requiring reliable sealing under continuous rotation.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of the equipment's housing and shaft. The shaft surface must be free of burrs, scratches or excessive wear; otherwise, the lip will not seal properly. During installation, lubricate the lip with the same oil or grease used in the equipment and place the seal perpendicular to the shaft, without striking it directly. If the shaft shows a worn track, consider slightly offsetting the seal or using a repair sleeve. Correct installation extends the service life of the seal and the associated bearings.
