The DBH 8903 is a radial shaft seal with the following dimensions: shaft diameter 52 mm, housing diameter 62 mm and height 10 mm. Its Lx design corresponds to a single sealing lip with a spring, intended for rotating shafts. The commercial designation is 8903 and the brand is DBH. This type of seal is press-fitted into the housing and its flexible lip runs on the shaft, creating a barrier against oil or grease leaks and against external dust.

Typical applications for a seal such as the DBH 8903 include gearboxes, pumps, electric motors, gear reducers and power transmission equipment. It is generally fitted at the point where a shaft exits a fixed housing, where there is lubricant that must be retained. It also appears in machine tools, process equipment and conveyor systems. It is always advisable to verify that the seal is compatible with the fluid, temperature and peripheral shaft speed before installing it.

To install the DBH 8903, clean the housing and the shaft, check that there are no burrs or excessive wear on the sealing surface, and lubricate the lip with the same oil or grease used in the equipment. Insert the seal perpendicularly, without striking the lip, using a tube or socket of the appropriate diameter. Seal selection depends on shaft speed, pressure and lubricant type; if the shaft has a deep groove, consider a wear sleeve or an alternative size.
