The DBH 9988 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and moisture from entering rotating shafts. With dimensions of 17 mm shaft, 25 mm housing and 3.50 mm height, and Lz design, it is mounted in gearboxes, pumps, electric motors and reducers. MR Accesorios Industriales supplies this brand and advises you to choose the correct seal for your equipment.

This DBH 9988 seal has a shaft diameter of 17 mm, a housing diameter of 25 mm and a height of 3.50 mm. Its Lz design indicates a configuration with a sealing lip and a spring that maintains pressure on the shaft. It is intended for rotating shafts where lubricant containment and contaminant exclusion are needed. The 9988 designation identifies the exact size within the DBH line, and it is important to verify that it matches the space available in your equipment.

Typical applications for this seal include gearboxes, water or oil pumps, low-power electric motors, reducers and spindles. It is also used in power transmission equipment and in agricultural or industrial machinery where the shaft rotates at moderate speeds. As a sealing component, it protects bearings and gears from particle ingress, extending the service life of the assembly.

To mount the seal correctly, verify that the shaft has the proper hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip before inserting it and avoid hitting it during assembly. Selection must consider rotation speed, working temperature and lubricant type. If the seal is damaged, replace it with one of the same dimensions and design to ensure efficient sealing.
