The DBH 5643 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating equipment. Its dimensions of 50 mm shaft, 68 mm housing and 14 mm height place it in a medium-size application, common in pumps, electric motors and gearboxes. MR Accesorios Industriales advises you so you choose the right seal for your equipment.

The DBH 5643 is a seal with an Mz design, with the dimensions indicated in its designation: 50 mm shaft diameter, 68 mm housing diameter and 14 mm height. The Mz design corresponds to a specific construction configuration from the manufacturer, which combines the sealing lip with a metal reinforcement and a secondary exclusion lip. It is used to retain oil or grease on rotating shafts and, at the same time, hold back dust and moisture from the environment.

Typical applications for this seal appear in equipment where a shaft rotates inside a fixed housing: centrifugal pumps, electric motors, gearboxes, mixers, fans and belt or chain drives. It is also found in agricultural and industrial machinery operating with dust or water present. In all these cases, the seal protects the bearings and prevents lubricant leaks.

To install it, check that the shaft has no burrs or wear and that the housing is clean and free of dents. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and do so with a flat pusher so as not to deform the seal. If the shaft shows a marked track, it is worth evaluating a seal with the lip in a different position or replacing the shaft. The selection depends on speed, temperature and the type of lubricant.

If you need a nearby size or an equivalent from another brand, send us code 5643 along with the shaft, housing and height dimensions, and the type of equipment where it is mounted. With that data we can look for an alternative within the same radial shaft seal category. If you do not have the dimensions, we can also guide you so you can take them directly on the equipment.
