The DBH 5491 radial shaft seal is a lip seal designed to close off the passage of oil or grease on rotating shafts and prevent the entry of dust and water. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains sealing. It is a common wear part in gearboxes, pumps, electric motors and transmission equipment, and is replaced when lubricant leakage or contaminant ingress appears.

This item is a DBH 5491 oil seal with the following dimensions: shaft diameter 45 mm, housing diameter 66 mm and height 6.00 mm. The indicated design is Lx, which corresponds to the lip and housing configuration. These values are what you have to verify before ordering: the seal is identified by those three dimensions and by the lip type. If your shaft or housing differs, a different size is needed.

Radial shaft seals of this type are used on shafts that rotate inside a fixed housing: gearboxes, centrifugal pumps, motors, rollers, mixers and power transmission equipment. They also appear in applications where grease must be retained in bearings or water and particles must be kept out. In all those cases the seal is an economical and frequently replaced barrier, so it is worth having the exact size identified.

To mount it, the housing must be clean and free of burrs, and the shaft free of splines or marks that could cut the lip. It is recommended to lubricate the lip before inserting it and to use a tube or support bushing so as not to deform it. Selection depends on shaft speed, temperature and the fluid to be retained; if those data are not defined, ask us and we will advise you. Do not force the seal with direct blows on the lip.

To quote 5491, send us the shaft, housing and height dimensions, plus a photo or the housing drawing. With that we look for the equivalent in the same brand or in another line we sell. We also tell you whether the Lx design is suitable for your application or whether a different lip type is better.
