This item is a DBH 9878 radial shaft seal, identified by its designation 9878. Its dimensions are: shaft diameter (d) 72 mm, housing diameter (D) 93.30 mm and height (h) 7.95 mm. The A 146 design corresponds to a specific construction within the DBH line. The sealing lip runs on the rotating shaft and the outer case is press-fitted into the housing. Always verify that these three dimensions match your equipment's housing and shaft before replacing.

Typical applications for an oil seal of this size include gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases it fulfills the function of confining the lubricant inside the assembly and preventing the entry of external contaminants, which extends the life of bearings and gears. It is a wear part: it should be checked at every preventive maintenance interval and replaced if it shows leaks, hardening or lip wear.

For correct installation, clean the housing and shaft, verify that there are no burrs or scratches and lubricate the lip before inserting it. The oil seal must go in perpendicular, without blows that deform the case. If the shaft shows wear, consider a design with an auxiliary lip. Selection depends on speed, temperature and lubricant type; with that data we can guide you to choose the right variant within the DBH line.
