The DBH 5491 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts and prevent the ingress 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 power 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 case configuration. These are the values you must verify before ordering: the seal is identified by these three dimensions and by the lip type. If your shaft or housing differs, a different size is required.

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 where water and particles must be kept out. In all these cases the seal is an economical and frequently replaced barrier, so it is advisable to have the exact size identified.

For installation, 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 to avoid deforming it. Selection depends on shaft speed, temperature and the fluid to be retained; if these data are not defined, consult us and we will guide you. Do not force the seal with direct blows on the lip.
