The DBH 8938 oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or chips. With a 55 mm shaft, 80 mm housing and 8 mm height, it is a common size in gearboxes, pumps and power transmission equipment. It is press-fitted into the housing and works with the lip resting on the rotating shaft.

This item is a DBH 8938 radial shaft seal, identified by its designation 8938 and by the dimensions shown on its product page: shaft diameter 55 mm, housing diameter 80 mm and height 8.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with permanent lubrication. DBH is a brand that MR carries, so the part number can be cross-referenced against the catalog to confirm the exact part.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all of these cases it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering that accelerate wear on bearings and gears. It is also used as a secondary closure in split plummer block housings and on fan shafts.

To install it, check that the shaft is within tolerance and free of burrs, and that the housing has no dents or scratches. Lubricate the lip before inserting it and seat the seal with a support tube that pushes on the outer edge, never on the lip. If the shaft shows a marked wear groove, consider a seal with an offset lip so it seals on a new track.

If you need an equivalent, send us the part number 8938 along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. With that data we review alternatives within the DBH line and other brands we carry, always confirming against the manufacturer's product page before quoting. We can also point you to the double-lip or reinforced-casing variant.
