The DBH 8431 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain the lubricant inside the housing and prevent contaminants, such as dust or water, from entering and damaging bearings and gears. It is installed in gearboxes, pumps, electric motors and other equipment where a shaft passes through a housing. With standardized dimensions, it is a common replacement part in industrial maintenance.

This DBH 8431 seal has a 35 mm shaft diameter, a 62 mm housing diameter and a height of 3.00/8.00 mm. Design A 038 corresponds to a single lip configuration with spring, suitable for applications rotating in both directions. The stepped height allows a firm fit in housings with a shoulder. It is a synthetic rubber part with metal reinforcement, designed to withstand continuous working conditions.

It is used in equipment where a shaft rotating inside a housing must be sealed: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools. It also appears in automotive and agricultural applications. Its 35 x 62 mm size is common on medium-sized power transmission shafts. As it is a wear component, it should be replaced when leaks or dirt ingress are detected.

To install it correctly, check that the shaft and housing are clean and free of burrs. Lubricate the lip with compatible grease before inserting it. The seal must enter perpendicular, without blows that deform the lip. If the shaft shows wear, consider a nearby size or a repair sleeve. The selection depends on speed, temperature and the type of fluid to be retained. If in doubt, consult the manufacturer's data sheet.
