The DBH 5405 is a radial shaft seal with an Lz design, meaning it has both a main sealing lip and an outer dust lip. It is used to keep oil or grease inside gearboxes, pumps and electric motors while blocking dust and water from entering. Its nominal dimensions are 25.4 mm shaft, 44.5 mm housing bore and 11.11 mm height.

In the DBH line, the number 5405 identifies this particular seal. The three dimensions you need to confirm are shaft 25.4 mm, housing 44.5 mm and width 11.11 mm. The Lz designation tells you the seal has a secondary dust lip in addition to the primary sealing lip, so it handles dirty or wet environments better than a single-lip seal. When you see 5405 on the old part or in the equipment manual, that is the reference to match.

Typical installations include gear reducers, centrifugal pumps, electric motors, mixers and conveyor rollers, as well as agricultural and industrial equipment exposed to dust, chips or washdown. In those conditions the dust lip keeps the main lip cleaner, which helps it seal effectively for longer.

Before pressing the seal in, inspect the shaft for burrs or deep grooves in the contact zone and make sure the housing bore is clean and round. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in straight using a tube or spacer that contacts only the outer diameter. Never push on the lip. If the shaft is worn, an offset-lip seal may be a better choice.

If you need a different size or an equivalent, send part number 5405 along with the shaft, housing bore and height measurements from your equipment. A photo of the old seal or the reference stamped on its edge also helps. We review options within the DBH line or from other brands we supply and confirm the technical data before quoting.
