The DBH 8018Sil is a radial shaft lip seal that sits between a rotating shaft and a stationary housing, keeping lubricant in and contaminants out. With a 66 mm shaft, an 85 mm housing bore and a 10 mm width, it fits medium-sized power transmission assemblies. Because the sealing lip wears over time, hardening or scoring leads to leaks, so replacing the seal early helps protect the bearing.

This seal belongs to the DBH line and carries the code 8018Sil. Its listed dimensions are shaft 66 mm, housing 85 mm and height 10 mm, with an Lz-R design. Lz-R refers to a lip seal with a reinforced configuration intended for continuous operation. The 8018Sil marking on the part is the reference to use when ordering a replacement.

Seals of this size are common in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment using oil or grease. They serve two purposes at once: retaining lubricant and blocking dust, water or particles from reaching the bearings. They are also chosen for older machinery where the housing bore is no longer perfect and a lip that tolerates some misalignment is needed.

Installation calls for a shaft free of burrs or wear at the contact zone and a clean, undented housing. Lubricate the lip before fitting, then seat it with a tube of the right diameter rather than striking the seal directly. If the shaft has a deep groove, a seal with the lip positioned differently may be the better choice. Speed, temperature and lubricant type all affect the final selection.

For an equivalent, send the code 8018Sil along with the shaft and housing dimensions and a photo of the part; the equipment brand and model also help. With that information, alternatives can be found within the DBH line or among other brands supplied. Advice is also available if the housing is damaged and a different size would work better.
