The DBH 8509Pol radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, motors and power transmission equipment with continuous rotation. Its Lx-R-AH design combines a sealing lip with a dust lip and a reinforced body, making it suitable for environments with moderate dirt.

This item is a seal from the DBH line, identified as 8509Pol. Its dimensions are: shaft diameter 90 mm, housing diameter 110 mm and height 8.50/10.00 mm. The Lx-R-AH design indicates a configuration with a sealing lip, a dust lip and a reinforced body, intended to retain lubricant and block external contaminants in applications with a rotating shaft. The double height allows the seal to fit in cavities with varying tolerances without losing contact.

Typical applications for this type of seal include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In these assemblies, the seal prevents oil or grease leaks and protects bearings and gears from the entry of dust, chips or water. It is also used on mixer shafts, conveyors and agricultural or industrial machinery where rotation is continuous and the environment may be aggressive.

To install a seal such as the 8509Pol, check that the shaft has the specified size and a surface free of burrs or deep marks; a scratched shaft accelerates lip wear. The housing must be clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the equipment operates with a lot of dirt, the dust lip helps, but it is advisable to evaluate a seal with greater protection.
