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 ingress of dust, water or particles. With a 30 mm shaft diameter, 50 mm housing diameter and 10 mm height, and Lz design, it is a very widespread size in pumps, electric motors, gear reducers and power transmission equipment. MR Accesorios Industriales supplies it as an official brand.

This item is a radial shaft seal from the DBH brand, identified by the part number 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, intended for rotating shafts with lubrication. The lip runs on the shaft and the outer case is press-fitted into the bore, so that the seal remains fixed to the housing and slides on the shaft.

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

To install it, check 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 presses 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.

If you need a nearby size or an equivalent, the most practical thing is to send us the part number 5289 together with the shaft, housing and height dimensions, and the design type if you know it. With that data we can look for an alternative within the same category of radial shaft seals or confirm whether there is an immediately larger or smaller size. It also helps if you tell us the equipment where it is installed and the brand of the original oil seal, if you have it at hand.
