The DBH 5289 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. With a 30 mm shaft diameter, 50 mm housing and 10 mm height, and Lz design, it is a very widespread size in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries it as a brand.

This item is a radial shaft seal from the DBH brand, identified with the code 5289. Its dimensions are 30 mm shaft diameter (d), 50 mm housing diameter (D) and 10 mm height (h). The Lz design corresponds to a seal with a sealing lip and spring, designed for rotating shafts with lubrication. The lip works on the shaft and the outer case is press-fitted into the bore, so the seal remains fixed to the housing and slides on the shaft.

Typical applications for a seal of this size include centrifugal pumps, electric motors, gearboxes, compressors, agitators and power transmission equipment. In all these cases it performs the same function: keeping the oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears. It is also used in washing equipment and agricultural machinery, where the seal must withstand splashes and dust.

To install it, verify that the shaft has no burrs or marks and that the sealing surface is polished; excessive roughness shortens the life of the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or shim that rests on the case, never on the lip. If the housing has a shoulder, respect the installation depth. When selecting, take into account the shaft speed, the working temperature and the type of lubricant.

To quote the code 5289, the most practical approach is to send it to us along with the shaft, housing and height dimensions, and the design type if you know it. With that data we can search for an alternative within the same category of radial shaft seals or confirm whether there is an immediate larger or smaller size. It also helps if you tell us the equipment where it is installed and the brand of the original seal, if you have it on hand.
