The DBH 9201 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft passes through a housing. It fits a 40 mm shaft, a 90 mm housing bore and a 12 mm width, and uses the Lx design. This makes it a common replacement item on gearboxes, pumps, motors and other transmission equipment built around 40 mm shafts. MR Industrial Accessories supplies it within its seals and oil seals range.

In the Lx construction the seal has a single sealing lip with a spring and no outer dust lip, so it is intended for open housings where the lip runs directly against the shaft. The 9201 code identifies both the size and the build type within the DBH line. The elastomer resists mineral oils and greases, and a metal case gives the seal the rigidity needed to press squarely into the bore.

Typical applications include gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools that turn on 40 mm shafts. The same seal also appears in agricultural and general industrial drives where bearings need protection from dust or water. Because it is a wear part, watch for oil loss, unusual noise or shaft play; those signs point to replacement.

To match a seal correctly, verify shaft 40 mm, housing 90 mm and width 12 mm, and inspect the shaft surface. A scored or worn shaft will not seal even with the right size. During installation, coat the lip with the same oil or grease used in the equipment, press the seal in perpendicular to the shaft and avoid impact. Remove burrs in the housing or steps on the shaft before fitting.

We can suggest equivalents from the DBH line or other brands we carry, always checking dimensions and lip style first.
