The DBH 8689 radial shaft seal is a lip seal that mounts on the shaft and in the housing to retain oil or grease and prevent the entry of dust and water. It is used in gear reducer cases, pumps, electric motors and power transmission equipment. MR Accesorios Industriales sells this brand and advises you so you choose the right seal for the application.

This item is a DBH 8689 radial shaft seal with the following dimensions: shaft diameter 48 mm, housing diameter 72 mm and height 10 mm. The Lx design indicates that it has a sealing lip and a dust lip, both with a spring. The main lip retains the lubricant and the secondary one protects against external contaminants. The designation 8689 identifies the size and the construction type within the DBH line.

Radial shaft seals are used in rotating equipment where the lubricant must be separated from the environment. Typical applications: gear cases, centrifugal pumps, electric motors, conveyor rollers and machine tools. They are also used in the food and chemical industry when the elastomer is compatible with the process fluids. In all cases, the seal works on a rotating shaft and inside a fixed housing.

To install a seal, verify that the shaft has the right hardness and surface finish, and that the housing is clean and free of burrs. The lip must be lubricated before installation and the seal must go in perpendicular to the shaft. If the shaft shows wear, a seal with an offset lip can be considered. The selection depends on speed, temperature and the fluid to be retained.
