The DBH 9411 radial shaft seal is a lip seal designed for rotating shafts, with dimensions of 40 mm inner diameter, 70 mm outer diameter and 8 mm height. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is a key part in gearboxes, pumps, electric motors and transmission equipment that operate with continuous movement.

This DBH 9411 oil seal has an Lx design, with a sealing lip and a metal body that is press-fitted into the housing. The nominal dimensions are 40 mm shaft diameter, 70 mm housing diameter and 8 mm height. The lip is made of an elastomer resistant to mineral oils and greases, and the internal spring maintains contact pressure on the shaft to compensate for small eccentricities.

It is used in equipment with rotating shafts where lubricant must be contained and contaminants blocked. Typical applications include gearboxes, centrifugal pumps, electric motors, mixers, conveyors and agricultural or industrial machinery. In all cases, the oil seal works together with bearings or bushings, and its correct selection prevents leaks and extends the service life of the assembly.

To install this oil seal, check that the shaft has the appropriate hardness and surface finish, with no burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the oil seal perpendicular to the shaft using an installation tube or press. If the housing shows wear, consider using an oil seal with a larger outer diameter or a repair sleeve.
