The DBH 5905 radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and stop the entry of dust, water or particles. Because of its size of 85 mm shaft, 130 mm housing and 13 mm height, it is used in transmission equipment and machinery with medium-section shafts. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal for your application.

This item is a DBH 5905 radial shaft seal, identified by its 5905 designation. Its dimensions are 85 mm shaft diameter (d), 130 mm housing diameter (D) and 13.00 mm height (h). The design is Lx, which defines the geometry of the lip and the metal body. It is a single-lip seal with an outer case, intended for rotating shafts where oil or grease must be contained and contaminants kept out. It is press fitted into the housing and runs supported on the shaft.

Typical applications for a seal of this size appear in gearboxes, pumps, electric motors, rollers and power transmission equipment. It is also used in agricultural, textile or continuous process machinery, where shafts rotate inside a lubricant-filled housing. In all cases it performs two functions: retaining the lubricant on the inner side and blocking dust or moisture from the environment. If the equipment operates with a lot of dirt or water, it is worth evaluating lip variants or alternative materials.

To install a seal, verify that the shaft is clean, free of burrs or marks, and that the sealing surface has the proper hardness and roughness. The housing must be in good condition and have the correct diameter so the seal enters under pressure without deforming. It is recommended to lubricate the lip before installing and to use an installation tool that presses evenly on the case, never on the lip. When selecting, take into account the shaft speed, working temperature and the fluid to be retained.
