The DBH 5778 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 38.10 mm shaft diameter, 57.15 mm housing diameter and 12.70 mm height make it suitable for equipment with 1.1/2 inch shafts. It is used in gearboxes, pumps, electric motors and transmissions, where reliable sealing extends bearing life and reduces maintenance. MR Accesorios Industriales carries this brand and advises you on choosing the right seal for your application.

This item is a DBH brand radial shaft seal, identified by the code 5778. Its dimensions are: shaft diameter (d) 38.10 mm, housing diameter (D) 57.15 mm and height (h) 12.70 mm. The Mz design corresponds to a configuration with a sealing lip and metal body, suitable for applications requiring a barrier against dust and lubricant. The 5778 designation makes it easy to locate in catalogs and replacement systems.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission shafts. In these machines, the seal prevents oil or grease leaks and protects the bearings from particle ingress. Its size is common on 1.1/2 inch shafts, so it is found in agricultural machinery, process equipment and production lines. It is a wear part that should be replaced during scheduled shutdowns.

For installation, verify that the shaft and housing are clean, free of burrs and scratches. Lubricate the seal lip with the same oil or grease used in the application before inserting it. Fit the seal perpendicular to the shaft, using a support tube that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. Selection must take into account speed, temperature and lubricant type.
