The DBH 9938 oil seal is a single-lip radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Its A 330 design and variable height of 11 to 15 mm allow it to be mounted in housings with different support depths. It is used in gearboxes, pumps, electric motors and industrial equipment where the shaft rotates within a moderate speed range. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct seal for your application.

This item is a DBH 9938 radial shaft seal with the following dimensions: shaft diameter 34 mm, housing diameter 55 mm and height 11.00/15.00 mm. The A 330 design corresponds to a sealing lip with spring and a secondary exclusion lip, mounted on a metal body. The variable height indicates that the outer section can adapt to housings with or without a shoulder, provided the bore diameter of the cavity is as specified. It is a standard replacement part for shafts requiring oil or grease containment.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all cases, the seal is installed in the cover or housing surrounding the shaft, with the lip facing the fluid to be retained. Its design with a secondary lip helps keep dirt out of the sealing area, extending the service life of the bearing and lubricant. It is commonly found in equipment where the shaft rotates at medium speeds and working conditions are demanding.

To correctly install this seal, verify that the shaft has a suitable surface finish and is free of burrs or wear in the contact area. The housing diameter must be within tolerance and the cavity must be clean and undamaged. Lubricate the lip with compatible grease or oil before installation and ensure the spring is properly seated. If the seal replaces another, compare dimensions and design to avoid premature leaks. If in doubt, consult our technical team.
