The DBH 8018Sil radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the ingress of dust, water or particles. Its dimensions of 66 mm shaft diameter, 85 mm housing diameter and 10 mm height place it in medium-sized power transmission equipment. It is a wear part: when the lip hardens or becomes marked, it starts to lose oil and should be replaced before the bearing fails.

This item is a seal from the DBH line, identified as 8018Sil. Its published attributes are: shaft diameter (d) 66 mm, housing diameter (D) 85 mm, height (h) 10 mm and Lz-R design. The Lz-R design corresponds to a seal with a sealing lip and a reinforced configuration for continuous service. The 8018Sil designation is the code you will find engraved or printed on the product and the one you should use when ordering a replacement.

Typical applications for a seal of this size are gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment with oil or grease lubrication. In all these cases it performs two functions at the same time: it prevents lubricant from escaping outward and stops contaminants from advancing toward the bearings. It is also used in older equipment where the housing already shows marks and a lip that works with some tolerance is needed.

To install it properly, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. The lip is lubricated before insertion and is seated with a tube of suitable diameter, never with direct blows on the seal. If the shaft shows a deep groove, consider a seal with the lip in another position. The final selection depends on the speed, temperature and type of lubricant of the equipment.

If you need an equivalent, send us the code 8018Sil along with the shaft and housing dimensions, a photo of the part and, if possible, the brand and model of the equipment. With that data we look for alternatives within the DBH line or from other brands we sell. We can also advise you if the housing is damaged and a different size is advisable.
