The DBH 8689 radial shaft seal is a lip seal mounted on the shaft and in the housing to retain oil or grease and prevent the ingress of dust and water. It is used in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales carries this brand and advises you so you choose the correct 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 spring. The main lip retains the lubricant and the secondary one protects against external contaminants. The designation 8689 identifies the size and 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: gearboxes, 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 appropriate 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 enter perpendicular to the shaft. If the shaft shows wear, a nearby size or a seal with an offset lip can be evaluated. The selection depends on speed, temperature and the fluid to be retained.
