The DBH 5558 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. Due to its dimensions of 44.45 mm shaft, 85.63 mm housing and 15.87 mm height, it is used in equipment where axial space is limited and a reliable seal is required. MR Accesorios Industriales carries this brand and advises you on choosing the correct seal.

This item is a DBH radial shaft seal, identified with the code 5558. Its dimensions are 44.45 mm shaft diameter, 85.63 mm housing diameter and 15.87 mm height. The Lx design corresponds to a single lip configuration with spring, intended for rotating shafts. The flexible lip rests on the shaft and creates a dynamic seal that prevents oil or grease leaks. The outer case is metallic and the elastomer withstands continuous contact with lubricants and service temperatures common in industrial equipment.

Seals of this size are found in gearboxes, pumps, electric motors, mixers and conveyors. They also appear in process equipment where the aim is to protect bearings and gears from external contamination. As it is a wear component, it should be checked when there are lubricant leaks, noise or vibration in the seal area. In applications with a lot of dust or water, the seal works alongside other sealing elements to keep the internal assembly clean.

To install a seal, verify that the shaft has no burrs, scratches or wear on the contact track. The surface must be clean and lubricated before inserting the seal. The housing must also be in good condition and free of deformation. It is recommended to use a tube or socket of suitable diameter to push the seal evenly, without striking the lip. If the shaft shows a marked groove, consider replacing it or using a size that moves the contact track. Correct alignment between shaft and housing is key to the service life of the seal.
