The DBH 5311Vit radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 20 mm shaft diameter, 42 mm housing diameter and 10 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the right size for your application.

This item is a DBH 5311Vit radial shaft seal, identified by its exact designation. Its attributes are: shaft diameter 20 mm, housing diameter 42 mm and height 10 mm. The Lx design corresponds to a single-lip seal with spring, designed to retain lubricant and exclude contaminants on rotating shafts. The elastomeric lip runs on the shaft and the metal case is press-fitted into the housing. It is a wear part that should be replaced when lubricant leakage or dust ingress appears.

Typical applications for a 20 x 42 x 10 mm oil seal include gearboxes, centrifugal pumps, electric motors, speed reducers, drive shafts and process equipment. In all cases it performs the function of sealing the passage of lubricant to the outside and preventing particles, water or vapors from entering. It is also used in machine tools, washing equipment and conveyor systems. If the equipment operates with heavy vibration or temperature, it is advisable to verify the compatibility of the elastomer with the fluid and the working conditions.

To install this oil seal, check that the shaft diameter is within tolerance and free of burrs, and that the housing has the correct diameter and depth. Lubricate the lip before inserting it and use an installation tube that bears on the case, never on the lip. Shaft runout and bearing clearance affect the service life of the seal. If the previous seal failed due to shaft wear, consider a repair sleeve or a nearby size before fitting the same size.
