The DBH 9931Pol oil seal is a single-lip radial shaft seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 24 mm shaft, 38 mm housing and 6 mm height, it is a compact size widely used in industrial equipment. MR Accesorios Industriales carries this brand and helps you confirm the correct variant before quoting.

The DBH 9931Pol is a radial shaft seal with an Lz-R H design: spring-loaded sealing lip, metal case and outer cover. Its dimensions are 24 mm shaft diameter (d), 38 mm housing diameter (D) and 6.00 mm height (h). The spring-loaded lip maintains contact on the shaft even with slight eccentricity, and the cover protects the elastomer during installation. It is a wear part: over time the lip hardens or gets marked and starts to leak oil.

It is used in gearboxes, pumps, electric motors, transmission shafts and process equipment where a shaft rotates inside a housing with lubricant. It also appears in applications exposed to dust or water, where the seal must stop contaminants from entering. In any of these cases, selection depends on shaft speed, working temperature and lubricant type, not only on the size.

To install it, make sure the shaft is clean, free of burrs or deep marks in the contact area, and lubricate the lip before sliding it on. The seal must go in perpendicular to the housing; if you hit it crooked, the lip gets damaged and leaks. When selecting, take into account the fluid to be retained, the temperature and the peripheral speed of the shaft. If the original seal has a different lip geometry or material, it is best to compare before replacing.

If you need an equivalent, send us the part number 9931Pol or the dimensions 24 x 38 x 6 mm and the type of application. With that we review alternatives within the same radial shaft seal category and confirm which option fits your equipment. We also tell you the variant with a different lip material or a different spring, depending on the fluid and working temperature.
