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 ingress of dust, water or particles that accelerate wear on bearings and bushings. It is a key component in gearboxes, pumps, electric motors and transmission equipment operating with continuous movement.

This DBH 9411 oil seal has an Lx design, with sealing lip and metal body that fits by pressure 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 seal works together with bearings or bushings, and its correct selection prevents leaks and extends the service life of the assembly.

To mount this seal, verify that the shaft has adequate hardness and surface finish, without burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it, and place the seal perpendicular to the shaft using a mounting tube or press. If the housing shows wear, evaluate the use of a seal with a larger outer diameter or a repair sleeve.
