The DBH 9639 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. With dimensions of 30 mm shaft diameter, 58.10 mm housing diameter and 11 mm height, and an Mz-R design, it is used in gearboxes, pumps, electric motors and industrial equipment that require reliable, long-lasting sealing.

This item is a DBH 9639 radial shaft seal, identified by its numerical designation. Its main attributes are: shaft diameter (d) of 30 mm, housing diameter (D) of 58.10 mm and height (h) of 11.00 mm. The Mz-R design corresponds to a configuration with a sealing lip and a spring that ensures constant contact on the shaft. These dimensions and features make it suitable for standard housings and shafts with specific tolerances.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all cases, its function is to prevent oil or grease leaks and protect bearings and gears from the entry of external contaminants. It is a critical part in industrial maintenance, since its failure can cause unscheduled downtime and costly damage to internal components.

For correct installation, verify that the shaft and housing diameters match the indicated dimensions. The shaft surface must be free of burrs, scratches or excessive wear; a suitable surface finish is recommended to extend the life of the lip. When installing, lubricate the lip with the same oil or grease used in the equipment and use an installation tool that applies uniform pressure on the outer ring, avoiding striking the sealing lip.
