The DBH 9255 is a single-lip radial oil seal built for rotating shafts. It fits a 20 mm shaft, a 38 mm housing bore and has a 5 mm height. Its job is to keep lubricant in and keep dust, water and particles out, protecting bearings and bushings from damage. You will find it in electric motors, pumps, gear reducers and other power transmission equipment, and it is typically replaced when leakage or contamination shows up.

This seal has an Lx design with a sealing lip and a retaining spring. The lip runs against the rotating shaft while the outer case seats in the housing. The lip elastomer is formulated to handle industrial oils and greases, and the spring keeps contact pressure over time. It suits assemblies where axial space is tight.

You will see the DBH 9255 in electric motors, centrifugal pumps, speed reducers, gearboxes, compressors, and belt or chain drives. It also appears in machine tools, conveyors and process equipment where a shaft turns inside a lubricated housing. In each case it stops leaks and shields nearby bearings or bushings. Because it is a common wear part, keeping it identified by its code helps you reorder without mistakes.

To select the right seal, confirm that shaft, housing bore and height match your equipment. Inspect the shaft surface: no burrs, scratches or heavy wear in the lip contact zone. During installation, lubricate the lip with the same oil or grease used in the machine, press the seal in perpendicular to the shaft, and avoid hitting it from the side. Use any housing chamfer to guide it. Misalignment or a damaged lip leads to early leaks.

If you need an equivalent, have the code 9255 and the current dimensions ready. We can search for alternatives within the DBH line or from other brands we supply, always matching shaft, housing bore and height. We can also help if the original has a special design, such as a double lip or a lip with a dust guard. The more you tell us — dimensions, lubricant type, working temperature and application — the better the match.
