The DBH 8938 oil seal is a single-lip radial shaft seal that mounts on the shaft and closes against the housing to retain lubricant and stop dust, water or chips from entering. With 55 mm shaft, 80 mm housing and 8 mm height, it is a commonly used size in gearboxes, pumps and 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 listed in its data sheet: 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 an official brand that MR carries, so the code 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 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, verify 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 place the seal with a support tube that pushes on the outer edge, never on the lip. If the shaft shows a marked groove, consider a nearby size or a seal with an offset lip so it seals on a new track.

If you need an equivalent or a close size, send us the code 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 data sheet before quoting. We can also check whether there is a variant with a double lip or reinforced case.

To close the inquiry, write to us on WhatsApp at MR Accesorios Industriales with the code 8938 or with the dimensions 55 x 80 x 8 mm. We will reply with the corresponding quote and equivalent alternatives. If the seal goes inside critical equipment, tell us the shaft type and working conditions so we can better guide you in the selection.
