The DBH 8162 radial shaft seal is a lip seal that closes off the passage of oil or grease on rotating shafts and prevents the entry of dust and water. With a 50 mm shaft diameter, 72 mm housing and 10 mm height, it press-fits 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 dimensions: 50.00 mm shaft diameter (d), 72.00 mm housing diameter (D) and 10.00 mm height (h). The Lx design indicates it has a main sealing lip and a secondary exclusion lip, mounted on a metal ring that fits into the housing. The lip elastomer works against the shaft, while the outer lip blocks dust and particles. It is a direct replacement component for equipment using 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. With 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, check that the shaft diameter is within the recommended tolerance for radial shaft seals and that the surface has no grooves or burrs. Lubricate the lip with the same grease or oil as the equipment before inserting it, and fit the seal with the lip facing the fluid side to be retained. The 10 mm height must fit into the housing without deforming; if it is too tight, slightly heat the housing. Do not strike the lip: use a tube or spacer that bears only on the outer ring.

If you need a seal with a different lip combination or an equivalent from another brand, send us the code 8162 and the shaft and housing dimensions. We can also search by application if you tell us the equipment and position. We work with the DBH line, so we can advise you on alternatives within the same radial seal category.
