The DBH 9211Vit radial shaft seal is a lip seal designed for rotating shafts with a 90 mm diameter. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles that accelerate the wear of bearings and bushings. It is press-fitted into the housing and works on the shaft surface, creating a reliable dynamic barrier in industrial equipment.

This item is a DBH model 9211Vit radial shaft seal with dimensions of 90.00 mm shaft diameter, 104.00 mm housing diameter and 11.00 mm height. Its Mx-R-AH design combines a sealing lip with a spring that maintains contact pressure on the shaft. The designation 9211Vit identifies the geometry and the lip compound, suitable for applications with moderate exposure to oils and greases.

Radial shaft seals such as the DBH 9211Vit are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. They also appear in agricultural machinery, packaging lines and pumping systems where preventing lubricant leaks and the entry of contaminants into the bearing is critical. Their mounting is common on shafts rotating at medium speeds and in housings with controlled tolerance.

To mount this seal, verify that the shaft has the appropriate hardness and roughness, without burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil as the equipment before inserting it. Place it perpendicular to the shaft, using a support tube that rests on the outer diameter, never on the lip. If the housing shows wear, evaluate a nearby size or a seal with a wear sleeve.
