The DBH 8159 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 38.54 mm shaft diameter, 50.80 mm housing diameter and height of 8.00/9.90 mm make it suitable for equipment with limited axial space. It is press-fitted into the cavity and runs on the shaft with an oil film that ensures sealing and low friction. It is a wear part that should be replaced at every preventive maintenance interval.

This item is a DBH brand radial shaft seal, identified by part number 8159. Its dimensions are 38.54 mm shaft diameter (d), 50.80 mm housing diameter (D) and a height that varies between 8.00 and 9.90 mm depending on the A 097 design. This stepped height allows better anchoring in the cavity and a more flexible sealing lip. The A 097 design corresponds to a single lip configuration with spring, suitable for general oil and grease retention applications.

Typical applications for this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. It is used on shafts rotating at moderate speeds and where lubricant leaks and the ingress of dust or water must be prevented. It is commonly found in agricultural machinery, construction equipment and industrial production lines. Its compact size makes it ideal for tight spaces where other seals do not fit.

For installation, check that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before installing. Insert the seal perpendicularly, without striking the lip, using a tube of suitable diameter that rests on the outer ring. Shaft runout must not exceed the values recommended for radial shaft seals. If the shaft shows wear, consider using a repair sleeve or an alternative size.
