The DBH 9841 seal is a single-lip radial seal that is mounted on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 25 mm shaft, 52 mm housing and 8 mm height place it in the range of medium-sized equipment, where it performs dynamic sealing functions in rotation. It is a wear part: when oil loss or dirt ingress appears, it is replaced with a seal of the same designation.

The DBH 9841 is a radial shaft seal with nominal dimensions of 25.00 mm shaft diameter, 52.00 mm housing diameter and 8.00 mm height. The Lx design corresponds to a single sealing lip with a retaining spring, intended for rotating shafts with permanent lubrication. The elastomeric lip rests on the shaft and the spring maintains contact pressure throughout its service life, while the outer body is fixed by interference in the housing. That combination is what defines its ability to retain oil and reject external contaminants.

Typical applications for a seal of this size are gear reducer boxes, centrifugal pumps, electric motors, transmission shafts and process equipment with bearings lubricated with oil or grease. In all these cases the seal performs two simultaneous functions: it prevents lubricant from leaking outward and it stops the ingress of dust, chips or water that degrade the bearing. It is also used in washing equipment, water pumps and agricultural machinery, where the working environment is demanding.

To select and install a seal, three things must be verified: that the shaft and housing diameters match the nominal size, that the height is compatible with the housing depth, and that the lip material is suitable for the working temperature and fluid. The shaft must be polished, free of burrs and wear marks in the contact area. When installing it, lubricate the lip and use a guide sleeve or cone so as not to damage it. If the shaft has a groove or wear, consider a seal with an offset lip or a repair sleeve.

If you need an equivalent, send us code 9841 along with the shaft, housing and height dimensions you have on the equipment. With that data we look for the alternative within the DBH line or other brands we sell. If the original seal has no legible identification, measure the shaft with a caliper and the housing with a micrometer, and also send us the type of fluid and the working temperature. That way we can guide you toward the option without guessing.
