The DBH 9815 radial shaft seal is a lip seal mounted between a rotating shaft and its housing to retain lubricant and stop dust, water or particles from entering. Due to its compact size, it is used in small gearboxes, electric motors, pumps and transmission equipment where axial space is limited. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct seal according to the shaft, housing and working conditions.

This item is an oil seal of design Mx with the following dimensions: shaft diameter 20 mm, housing diameter 31.75 mm and height 6.00 mm. The sealing lip runs on the shaft and the outer case fits into the housing. The designation 9815 identifies the size within the DBH catalogue. Before installing it, verify that the shaft and housing match these values, because even a minimal difference prevents correct sealing or causes leaks.

Typical applications for a seal of this size include small electric motors, gearboxes, centrifugal pumps, compressors, machine tools and belt or chain transmission equipment. In all cases it fulfills the function of retaining the oil or grease of the bearing and preventing contaminants from entering. It is also used as a barrier in gearboxes and mechanisms where the shaft rotates at moderate speeds and the temperature does not exceed the usual limits of the material.

To select it properly, take into account the shaft speed, working temperature and type of lubricant. Design Mx corresponds to a single lip configuration with spring, suitable for rotating shafts with little misalignment. When installing it, lubricate the lip, verify that the shaft has no burrs or marks and place the seal perpendicular to the shaft. If the housing is damaged or the shaft is worn, sealing may fail even if the size is correct.
