The DBH 8447 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and water ingress on rotating shafts. With a 15.60 mm shaft diameter, 24.00 mm housing diameter and 7.00 mm height, it is press-fitted into crankcases, covers and gearboxes. Its Lx design combines a sealing lip with a dust lip, making it suitable for environments with moderate dirt. MR Accesorios Industriales sells it.

This item is an oil seal from the DBH line, identified by part number 8447. Its dimensions are shaft (d) 15.60 mm, housing (D) 24.00 mm and height (h) 7.00 mm. The Lx design indicates a configuration with a main sealing lip and an auxiliary exclusion lip, designed to retain lubricant while also stopping contaminant ingress. The lip elastomer runs on the shaft with slight interference, while the outer diameter maintains the fit in the housing. It is a common replacement part in equipment with small-diameter shafts.

It is used in electric motors, centrifugal pumps, speed reducers, compressors and machine tools. It also appears on drive shafts of light agricultural and industrial equipment. Its function is twofold: keep the lubricant inside the assembly and prevent particles from entering that would accelerate wear on bearings and bushings. In applications with splashes or dust, the dust lip of the Lx design helps keep the sealing area clean.

To install it, check that the shaft has no burrs or deep marks and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it. Pressure must be even, applied on the outer ring, never on the lip. If the shaft shows wear, consider a seal with the lip in another position. The choice depends on speed, temperature and the type of lubricant.

If you need an equivalent, send us part number 8447 along with the shaft, housing and height dimensions. A photo of the old seal or the assembly drawing also works. With that data we look for alternatives within the DBH line or from other brands we sell. Not all dimension combinations are standardized, so it is best to confirm against the manufacturer's product page before replacing.
