The DBH 5890 radial shaft seal is a lip seal that is mounted in the housing and closes against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 52.4 mm shaft, 81 mm housing and 11 mm height place it in medium-sized transmission equipment. It is a wear part: when oil loss or dirt ingress appears, it is replaced. MR Accesorios Industriales carries this brand and advises you so you can choose the right seal.

This item is a DBH radial shaft seal, code 5890, with the following dimensions: shaft diameter 52.4 mm, housing diameter 81 mm and height 11 mm. The design indicated is Lx, which corresponds to a seal with a sealing lip and a metal reinforcement structure, suitable for press fitting into the housing. The lip works on the shaft and, depending on the case, may include a spring that maintains contact pressure. The designation 5890 identifies this size within the DBH line.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where there is a rotating shaft coming out of a lubricated crankcase. They also appear in road machinery, agricultural machinery and permanent plant equipment. The function is twofold: to prevent oil or grease from escaping and to prevent dust, wash water or contaminants from entering the bearing or the gear. In environments with a lot of dirt or frequent washing, the seal is the first barrier.

To select the seal, verify that the three dimensions match the shaft, the housing and the seat depth. The shaft surface must be ground and free of burrs; a mark or wear on the sealing track causes leaks even if the seal is new. When mounting, lubricate the lip with the same grease or oil as the equipment, insert it perpendicular to the shaft and strike only on the outer ring, never on the lip. If the housing has burrs, clean before inserting the seal.

If you cannot find code 5890 or you need a nearby size, send us the shaft, housing and height dimensions, plus a photo of the old seal if possible. The code engraved on the seal or the equipment model also helps. With that data we look for the equivalent in the same brand or in another line we carry. If the Lx design is not the right one for your application, we review it with you.
