The DBH 5231 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block dust, water or particles from entering. With dimensions of 45 mm shaft, 65 mm housing and 8 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the correct oil seal for your application.

This item is a radial shaft seal from the DBH line, identified with the code 5231. Its dimensions are 45.00 mm shaft diameter (d), 65.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to an oil seal with a sealing lip and a standard configuration for rotating shafts. The lip elastomer and the internal spring work together to maintain contact on the shaft and compensate for small misalignments. It is a common replacement component in industrial maintenance.

Typical applications for an oil seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases it serves to retain the oil or grease inside the assembly and prevent contaminants from entering from outside. It is also used on fan, mixer and conveyor shafts, where sealing prevents lubricant loss and premature wear of bearings and bushings.

To install a radial shaft seal, check that the shaft and housing are clean, free of burrs or marks, and lubricate the lip before inserting it. The seal must enter perpendicular to the shaft, without blows that deform the casing. When selecting, take into account the rotation speed, working temperature and type of lubricant, because they determine the lip material and the spring. If the shaft shows wear, consider a repair sleeve before installing the new seal.

If you need an equivalent or a different size, send us the full code, the shaft, housing and height dimensions, and a photo or sample of the original oil seal. With that data we can look for the alternative within the DBH line or from other brands we carry. We can also advise you if the Lx design is not suitable for your equipment and it is worth evaluating another lip or casing configuration.
