The DBH 9409 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. It mounts in a cylindrical housing and seals against the shaft. With an Lx design, it measures 40 mm shaft diameter, 90 mm housing diameter, and 8.00 mm height. This seal is commonly used in gearboxes, pumps, electric motors, and transmission equipment operating with oil or grease. MR Industrial Accessories supplies this brand and can help you select the correct seal for your application.
The DBH 9409 belongs to the DBH line, where 9409 denotes this particular size. The Lx design indicates a seal configuration suitable for moderate shaft speeds and permanent lubrication. When selecting a replacement, the critical dimensions are shaft diameter (d) 40 mm, housing diameter (D) 90 mm, and height (h) 8.00 mm. These must match your equipment to ensure proper fit and sealing.
Typical applications include gearboxes, centrifugal pumps, electric motors, rollers, and power transmission components. The seal separates lubricant from the environment, protecting bearings and bushings from dust, water, and particles. It is also found in machine tools and process equipment where oil containment is required. In all cases, the seal's performance depends on correct installation and appropriate operating conditions.
Before installation, verify that the shaft measures 40 mm and the housing bore 90 mm, with a smooth surface finish free of burrs. The 8.00 mm height must fit the housing depth. Lubricate the lip before pressing the seal into place, and use a proper installation tool to avoid damaging the lip. If your equipment sees high vibration or temperature, ask about available compound options. Proper alignment of shaft and housing will help extend seal life.
