The DBH 9239 radial shaft seal is a lip seal that closes off the passage of lubricant and blocks the entry of dust, water or particles on rotating shafts. It is press-fitted into the housing and works on the shaft with a flexible lip that compensates for small misalignments. It is a wear part: when oil loss, weeping around the seal area or dirt ingress appears, it is replaced. This model, with a 10.80 mm shaft, 20.00 mm housing and 9.00 mm height, with Lx design, covers compact low- and medium-demand applications.

The DBH 9239 is a shaft seal with the following dimensions: shaft diameter d 10.80 mm, housing diameter D 20.00 mm and height h 9.00 mm. The indicated design is Lx, which corresponds to the manufacturer's lip and case configuration. These three dimensions define the installation: the housing must accommodate the outer diameter and the shaft must enter with the intended fit on the lip. Before ordering a replacement, it is advisable to measure all three with a caliper and compare them with the old part.

Typical applications for an oil seal of this size are small-diameter shafts in compact equipment: small electric motors, reducers, pumps, fans, power transmission machines and process equipment where the goal is to retain oil or grease and prevent the entry of contaminants. It is also used in drive mechanisms, rollers and transmission shafts rotating at moderate speeds. In all cases it performs the same function: separating the lubricated side from the environment.

To select and install an oil seal, you must verify the shaft diameter, the housing diameter and the height, and respect the mounting direction of the lip: the edge must face the side of the fluid to be retained. The shaft surface must be clean, free of burrs and marks, and it is advisable to lubricate the lip before inserting it. The seal is placed perpendicular to the shaft and pressed in evenly, without striking the lip. If the shaft shows wear, the new lip may not seal even if the size is correct.

To quote the 9239, send us the three dimensions —shaft, housing and height— and the type of fluid or application. With that data we look for the equivalent oil seal in the DBH line or in another brand we supply, and we confirm alternatives. We can also guide you if the Lx design is not suitable for your case and a different type of lip or case is needed.
