The DBH 8162 radial shaft seal is a lip seal that closes off the passage of oil or grease on rotating shafts and prevents dust and water from entering. With 50 mm shaft diameter, 72 mm housing and 10 mm height, it is press-fitted into crankcases, gearboxes and pumps. Its Lx design combines a sealing lip with a dust lip, making it suitable for environments with moderate dirt.

This item is a DBH 8162 oil seal, identified by its numeric designation and its dimensions: 50.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 10.00 mm height (h). The Lx design indicates that it has a main sealing lip and a secondary exclusion lip, mounted on a metal ring that fits into the housing. The lip elastomer runs against the shaft, while the outer lip blocks dust and particles. It is a direct replacement component for equipment that uses this standard size.

It is used on transmission shafts, gearboxes, centrifugal pumps, electric motors and machinery rollers. It also appears in washing equipment, mixers and conveyors where there is contact with water or dust. Because it has a double lip, the 8162 seal performs well in areas exposed to dirt, provided the shaft is ground and the rotation speed is not extreme. It is a wear part: it should be checked at every preventive maintenance interval and replaced if it shows cuts, hardening or loss of elasticity.

To install it, verify that the shaft diameter is within the tolerance recommended for radial shaft seals and that the surface has no scores or burrs. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal with the lip facing the side of the fluid to be retained. The 10 mm height must fit into the housing without deforming; if it is very tight, slightly heat the housing. Do not strike the lip: use a tube or spacer that rests only on the outer ring.
