The DBH 5553 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain the lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. With dimensions of 40 mm shaft diameter, 65 mm housing and 12 mm height, and an Lx design, it is used in gearboxes, pumps, electric motors and industrial equipment in general. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

The DBH 5553 is a radial type seal with a sealing lip. Its dimensions are 40.00 mm shaft diameter (d), 65.00 mm housing diameter (D) and 12.00 mm height (h). The Lx design indicates a specific construction configuration that combines a main lip with a secondary exclusion lip, although the exact geometry is confirmed against the manufacturer's data sheet. The lip elastomer and the internal spring guarantee sealing under continuous rotation conditions.

This seal is used in applications where there is a shaft rotating inside a fixed housing. It is common in gearboxes, centrifugal pumps, electric motors, compressors, spindles and transmission equipment. It is also found in agricultural machinery, mining equipment and process lines where it is required to contain oil or grease and protect the bearings from the environment. Its Lx design makes it suitable for environments with moderate presence of dust or moisture.

To install the seal, verify that the shaft has no burrs or wear and that the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Removal must be done with a suitable tool to avoid damaging the seat. When selecting a replacement, in addition to the dimensions, take into account the peripheral speed, working temperature and the type of fluid to be retained. If the shaft shows wear, consider a repair sleeve.
