The DBH 5405 radial shaft seal is a lip seal that mounts on the shaft and closes off the passage of oil, grease or contaminants in gearboxes, pumps and electric motors. Its Lz design combines a sealing lip with a dust lip that protects the contact area. With dimensions of 25.4 mm shaft, 44.5 mm housing bore and 11.11 mm height, it is a common replacement part in power transmission equipment.

This item is a radial shaft seal from the DBH line, identified by part number 5405. Its nominal dimensions are 25.4 mm shaft diameter (d), 44.5 mm housing bore diameter (D) and 11.11 mm height (h). The Lz design corresponds to an oil seal with a main sealing lip and an outer dust lip, designed to retain lubricant and stop dust or water from entering from the environment. The 5405 designation is the reference you will find on the manufacturer's product page to order the exact replacement.

It is used in equipment where a rotating shaft passes through a lubricated housing: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyor rollers. It also appears in agricultural and industrial applications where the oil seal must withstand dust, chips or wash water. In these cases the dust lip of the Lz design helps the main lip work cleaner and last longer.

To mount it correctly, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil as the equipment before inserting it, and press the part in straight with a tube or spacer that pushes on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or an oil seal with an offset lip.

If you need an equivalent or a different size, send us part number 5405 together with the shaft, housing bore and height dimensions shown on the equipment. A photo of the old oil seal or the reference engraved on the edge also works. With that data we review alternatives within the same DBH line or from other brands we supply, always confirming the technical data before quoting.

MR Accesorios Industriales supplies the DBH brand as part of its line of seals and oil seals. If you have doubts about the designation, the size or the type of lip, write to us on WhatsApp with part number 5405 and we will help you identify the correct part for your equipment.
