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 lubrication and continuous contact. It is a standard replacement part within the line of seals 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, verify 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 design change. Selection depends on speed, temperature and the type of lubricant, data that should be confirmed before requesting a quote.
