This item is a DBH radial shaft seal, identified by code 5590. Its dimensions are 44.45 mm shaft diameter (d), 63.55 mm housing bore diameter (D) and 7.93 mm height (h). The Mz design corresponds to a seal with a sealing lip and a reinforcement structure that ensures it stays in the housing. It is intended for rotating shafts where a barrier against oil or grease leaks and against the ingress of dust or water is required.

Typical applications for this seal include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In these assemblies, the seal sits in the housing and its lip runs against the shaft to retain lubricant. It is also used on rollers and shafts of road or agricultural machinery, where the environment is demanding and reliable sealing is required to extend bearing life.

To correctly select and install this seal, verify that the shaft and housing dimensions match 44.45 mm and 63.55 mm respectively. The 7.93 mm height must fit into the cavity without forcing. During installation, lubricate the lip with the same oil or grease used in the equipment, avoid striking it and make sure the shaft has no burrs or excessive wear. If the shaft shows a marked track, consider slightly repositioning the seal or replacing the shaft.
