The DBH 5025Sil radial shaft seal is a lip seal designed for rotating shafts. With dimensions of 20 mm shaft diameter, 40 mm housing bore and 6 mm height, this component prevents oil or grease leaks and blocks the ingress of dust and moisture. It is a key part in gearboxes, pumps and motors, where correct sealing extends the service life of bearings and gears. MR Accesorios Industriales supplies this brand and advises you so you can choose the right seal.

This item is a radial shaft seal from the DBH line, identified by the designation 5025Sil. Its dimensions are: shaft diameter (d) 20 mm, housing bore diameter (D) 40 mm and height (h) 6.00 mm. The Lx design indicates a configuration with a sealing lip and a spring that ensures constant contact on the shaft. It is manufactured with elastomers resistant to oils and greases, and its outer metal structure facilitates press-fit mounting in the housing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission systems. In all these machines, the 5025Sil seal retains lubricant and excludes external contaminants. It is commonly found in industrial machinery, agricultural equipment and vehicles, where working conditions demand reliable and long-lasting sealing.

For correct installation, verify that the shaft and housing are clean and free of burrs. Lubricate the seal lip with the same oil or grease used in the equipment before inserting it. The installation tool must press on the outer ring, never on the lip, and pressure must be uniform until the seal seats at the bottom of the housing. If the shaft shows wear, consider using a seal with an auxiliary lip or a wear sleeve.
