The DBH 5401 radial shaft seal is a lip seal that is mounted on the shaft and closes against the housing to retain the lubricant and stop the ingress of dust, water or particles. Its Lz design combines a sealing lip with a dust lip, which makes it useful in equipment with moderate exposure to contaminants. It is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates on bearings or bushings and oil or grease must be contained.

This item is a DBH radial shaft seal with the designation 5401. Its dimensions are 22.22 mm shaft diameter, 41.25 mm housing diameter and 11.11 mm height. The Lz design indicates that it has a main sealing lip and an outer dust lip, intended to protect the sealing area when there is dust or splashing. The elastomer and the internal spring are not detailed in the record, so those data are confirmed against the manufacturer's data sheet before quoting.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment where the shaft passes through a cover or housing. It is also found in machine tools, washing equipment and conveying systems that need to contain grease or oil and prevent dirt from entering. In all cases, the seal works together with a bearing, a bushing or a housing that defines the concentricity of the shaft.

To install it properly, verify that the shaft diameter and the housing diameter match the indicated values, that the shaft has no burrs or marks and that the housing is clean and free of old sealant residue. Lubricate the lip before sliding it on and use a tube or socket of adequate diameter to support the seal and strike it evenly, never on the lip. If the equipment works with a lot of vibration or misalignment, it is advisable to also check the condition of the bearing and the roughness of the shaft.
