The DBH 5742 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. Its dimensions of 77.80 mm shaft, 111.02 mm housing and 14.28 mm height place it in transmission equipment and medium-size machinery. MR Accesorios Industriales sells it as an official brand, with technical advice so you can choose the right variant for your application.

This item is a DBH 5742 radial shaft seal, identified by its designation 5742. It runs on a shaft of 77.80 mm diameter and fits into a bore of 111.02 mm, with a total height of 14.28 mm. The Lz design defines the geometry of the lip and the metal body, intended for applications with continuous lubrication and contact. It is a standard replacement part within the seal line that MR sells.

Radial shaft seals of this size are used in gearboxes, pumps, electric motors, transmission shafts and process equipment where oil must be separated from the environment. They also appear in agricultural machinery, conveyors and pumping systems operating with exposure to dust or moisture. In all these cases, the seal protects the bearings and prevents leaks that dirty the equipment and force a shutdown.

To install it, check that the shaft has no burrs or wear and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the shaft shows a marked track, consider a neighboring size or a design change. The selection depends on speed, temperature and the type of lubricant, data worth confirming before requesting a quote.

We can also guide you if the original seal is no longer available or if the shaft has been reground.
