The DBH 9931Pol is a radial shaft seal sized for a 24 mm shaft, a 38 mm housing bore and a 6.00 mm height. Its job is to hold lubricant inside the housing while keeping dust, water and particles out along the rotating shaft. This compact size shows up in a wide range of industrial equipment. MR Industrial Accessories supplies the DBH brand and can confirm the right variant before preparing a quote.

In the DBH designation, the seal is built with an Lz-R H configuration: a spring-loaded sealing lip, a metal case and an outer cover. Reading the size is straightforward: shaft 24 mm, housing 38 mm, width 6.00 mm. Because the lip is spring-loaded, it keeps pressure on the shaft even when there is slight eccentricity, and the cover shields the elastomer while the seal is being pressed in. Like any seal of this type, it is a wear part. Once the lip hardens or picks up marks, oil starts to escape.

Typical locations include gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft turns inside a lubricated housing. The same seal also appears in areas where dust or water is present and has to be kept away from the bearing cavity. Size alone does not settle the choice: shaft speed, operating temperature and the lubricant in use all influence which variant works best.

Installation calls for a clean shaft with no burrs or deep scoring across the contact band, and a light film of lubricant on the lip before it slides into place. The seal has to enter the housing squarely; driving it in at an angle damages the lip and creates a leak path. During selection, consider the fluid being retained, the temperature and the peripheral speed of the shaft. If the seal being replaced has a different lip profile or elastomer, compare the two before committing.

For an equivalent, send the part number 9931Pol or the dimensions 24 x 38 x 6 mm along with the application details. From there we can look at options within the same radial shaft seal category and confirm which one suits your equipment. We can also point you to a version with a different lip material or spring when the fluid or working temperature calls for it.
