This item is a DBH 6903 radial shaft seal, identified by its designation 6903. Its dimensions are 24 mm shaft diameter (d), 37 mm housing diameter (D) and 4.80 mm height (h). The Lx design corresponds to a seal with a single sealing lip and spring, suitable for rotating lubricated shafts. The DBH brand is a brand that MR sells, so you can ask us about this size and other equivalents.

Typical applications for a seal of this size include centrifugal pumps, electric motors, gearboxes, compressors, machine tools and transmission equipment. In all cases, its function is to prevent oil or grease leaks and protect bearings and gears from the entry of contaminants. It is also used in applications where axial space is limited, since its 4.80 mm height allows it to be mounted in compact housings.

To install a radial shaft seal correctly, verify that the shaft has the proper hardness and roughness, free of burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The seal must sit perpendicular to the shaft and fully seated in the housing. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. Always confirm the housing and shaft tolerances against the manufacturer's data sheet.

If you need an equivalent seal or a nearby size, send us the full part number, the shaft and housing dimensions, and a photo of the part. With that data we can look for alternatives in the same series or in other brands we sell. We can also advise you on the lip type, elastomer material and spring according to the working conditions: temperature, speed and type of lubricant.
