The DBH 5231Pol radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles, protecting bearings, bushings and gears. With a 45 mm shaft, 65 mm housing and 8 mm height, it is a commonly used size in industrial and agricultural equipment. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a DBH oil seal with the designation 5231Pol, with the following dimensions: shaft diameter 45 mm, housing diameter 65 mm and height 8.00 mm. The indicated design is Lx, a single lip profile with a spring that runs on rotating shafts. The code 5231Pol identifies the part within the DBH line and it is best to quote it in full when ordering a replacement, because the same size may exist in other designs.

Seals of this size appear in gearbox housings, centrifugal pumps, electric motors, drive shafts, rollers and process equipment. They are also used in agricultural machinery, where dust and moisture demand a reliable seal. When the seal fails, loss of lubricant or entry of contaminants accelerates wear on bearings and gears, so it is best to replace it at every teardown of the assembly.

To select the seal correctly, verify that the shaft diameter and the housing diameter match the original part, and that the height is compatible with the housing depth. The Lx design runs with the lip resting on the shaft; check that the shaft surface has no burrs, deep scratches or wear. During installation, lubricate the lip, insert it perpendicular to the shaft and avoid striking it from the side. If the shaft shows a marked groove, consider shifting the seal slightly or using a wear sleeve.

If you need an equivalent or a nearby size, send us the code 5231Pol along with the shaft, housing and height dimensions, and the type of equipment where it is mounted. With that data we can look for an alternative within the DBH line or other brands we carry. It also helps if you send a photo of the old seal and the housing, so we can confirm the design and avoid ordering errors.
