The DBH 9812/85 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 23 mm shaft, 34.50 mm housing bore and 7.50 mm height place it in small and medium-sized equipment. It is used in gearboxes, pumps, electric motors and mechanisms with rotary motion where a reliable, low-maintenance barrier is needed.

This item is a radial shaft seal from the DBH line, identified as 9812/85 with an A 192 design. Its dimensions are 23 mm shaft diameter, 34.50 mm housing bore diameter and 7.50 mm height. The flexible lip runs on the rotating shaft and the outer case fits into the housing cavity. That combination of dimensions corresponds to a compact-section seal, intended for tight spaces where a taller seal does not fit.

Typical applications appear in rotating equipment: gearboxes, centrifugal pumps, electric motors, reducers, mixers and belt or chain drives. It is also found in machine tools, washing equipment and conveyor systems. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear on bearings and gears.

To install it properly, verify that the shaft is clean, free of burrs or marks, and that the running surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal with a tube or driver that presses on the outer edge, never on the lip. If the housing has a shoulder, respect the seating depth. A poorly installed seal loses tightness within a few hours, even if its dimensions are correct.

If you need an equivalent or a nearby size, send us the code 9812/85 along with the shaft, housing and height dimensions, and a photo or sketch of the housing. With that data we look for alternatives in the same category or in other brands we carry. We can also advise you if the A 192 design is not the right one for your application and a different lip type or material is better suited.
