The DBH 5227Sil radial shaft seal is a lip seal mounted on the shaft that closes against the housing to retain lubricant and stop the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment where there is a shaft rotating inside a fixed body. Its dimensions of 48 mm shaft, 65 mm housing and 10.50 mm height place it in the medium range of seals for industrial use.

The 5227Sil from DBH is a seal with an Lz design, with the three dimensions that define its mounting: 48 mm shaft diameter, 65 mm housing diameter and 10.50 mm total height. The Lz design corresponds to a seal with a sealing lip and a retaining spring, intended for rotating shafts with lubrication. The 5227Sil nomenclature identifies the part within the DBH line and it is worth quoting it in full when ordering it, together with the dimensions, to avoid confusion with seals of similar section.

These seals appear in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. They are also found in agricultural machinery, washing equipment and systems where the shaft passes through a metal wall and two environments must be separated: one with oil or grease and another exposed to dirt or moisture. In all those cases the seal serves the dual function of containing the lubricant and acting as a barrier against external contaminants.

To select a seal you must verify the shaft diameter, the housing diameter and the available height. The housing must be clean, free of burrs or tool marks, and the shaft free of splines or wear in the contact area, because a scratched surface ruins the lip in a few hours. When mounting it, lubricate the lip with the same oil as the equipment and use a tube or press that bears on the outer edge, never on the lip. If the shaft has a shoulder or keyway, protect the lip with a sleeve before sliding it on.

If you need a nearby size or an equivalent from another brand, send us the full code and the three dimensions: shaft diameter, housing diameter and height. With that data we can search within the DBH line or cross-reference with other options we carry. If the original seal has no legible identification, measure the shaft and the housing with a caliper and send us those values; we confirm the part against the manufacturer's data sheet before quoting you.
