The DBH 9631/85 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Due to its dimensions —39.9 mm shaft, 45.8 mm housing and 5.50/7.20 mm height— it is used in gearboxes, pumps and power transmission equipment where axial space is limited. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

This item is a seal from the DBH line, identified by the designation 9631/85. Its dimensions are: shaft diameter 39.9 mm, housing diameter 45.8 mm and height 5.50/7.20 mm. The A 266 design corresponds to a profile with a sealing lip and metal body, suitable for press fitting into a cylindrical housing. The double height indicates that the seal has a main lip and a protective section against the ingress of dust or dirt.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases, the function is to prevent oil or grease leaks and block the passage of external particles. Because its shaft diameter is close to 40 mm, it is common in medium-power equipment, where reliable sealing is required with little radial space.

To select correctly, verify that the shaft and housing diameters match the indicated values. The 5.50/7.20 mm height must respect the cavity depth. Installation is done with the proper tool, without striking the lip, and with the shaft clean and lubricated. Shaft runout and roughness influence service life: a fine finish without burrs favors sealing.
