The DBH 8412Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 30 mm shaft diameter, 43 mm housing and 8 mm height, and an Mz-R design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified with code 8412Pol. Its standardized dimensions are: shaft diameter 30 mm, housing diameter 43 mm and height 8.00 mm. The Mz-R design corresponds to a configuration with sealing lip and spring, suitable for rotating shafts with lubrication. The lip elastomer and the metal body are designed to withstand continuous friction and maintain sealing. It is a wear part that is replaced during preventive or corrective maintenance.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. It is also used in machine tools, conveyors and agricultural or road equipment. In all cases, its function is to confine the oil or grease inside the assembly and protect the bearings and gears from external contamination, extending the service life of the components.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Mz-R design is suitable for shafts with rotation in one direction and moderate speeds; if your application requires another configuration, consult us. During mounting, lubricate the lip with the same oil used in the equipment, insert the seal perpendicularly and avoid striking it. Make sure the shaft has no burrs or wear that could damage the lip.
