The DBH 8909 radial shaft seal is a lip seal designed for 42 mm rotating shafts, with a 68 mm housing and 10 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or contaminating particles. It is used in gearboxes, pumps, electric motors and transmission equipment where maintaining sealing is critical. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal for your application.

This item is a seal from the DBH line, identified by the part number 8909. Its nominal dimensions are: shaft diameter 42 mm, housing diameter 68 mm and height 10 mm. The Lx design corresponds to a seal with a single sealing lip and spring, suitable for rotating shafts with lubrication. The 8909 designation makes it easy to locate in the catalog and confirm that the dimensions match the housing and shaft of your equipment.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain transmission systems. In all cases, the 8909 seal protects bearings and gears from contaminant ingress and prevents oil or grease leaks. It is a wear part that should be replaced when leaks or abnormal noises are detected in the seal area.

To install the seal correctly, check that the shaft has no burrs or wear and that the sealing surface is clean. Lubricate the lip with the same oil or grease as the equipment before inserting it. The housing must be free of impacts and have the proper chamfer so as not to damage the lip. If the shaft has a deep groove, consider using a seal with a wear sleeve or an alternative size.
