The DBH 9120 radial shaft seal is a lip seal that mounts between a rotating shaft and its housing to retain lubricant and stop the entry of dust, water or particles. Due to its dimensions of 35 mm shaft, 47 mm housing and 10 mm height, it is a common replacement part in gearboxes, pumps and medium-sized electric motors. At MR Accesorios Industriales we carry it as part of our seals and oil seals line.

The DBH 9120 is a seal with an Lx design, with a sealing lip and metal body. Its dimensions are 35 mm shaft diameter, 47 mm housing diameter and 10 mm height. The Lx design corresponds to a seal with a single lip and spring, intended for rotating shafts with permanent lubrication. The designation 9120 identifies the size within the DBH line and is the reference worth keeping on hand when replacing it.

It is used in equipment where oil or grease must be separated from the environment: gearboxes, centrifugal pumps, electric motors, speed reducers and conveyor rollers. It also appears in machine tools and process equipment where the shaft rotates continuously. In all these cases it performs two functions: preventing lubricant leaks and blocking the entry of contaminants that wear down bearings and gears.

To choose a seal correctly, you must verify three things: that the shaft diameter is 35 mm, that the housing is 47 mm and that the available width is 10 mm. Also check the condition of the shaft surface: if it has scratches or wear, the lip will not seal even if the size is correct. When mounting it, lubricate the lip, seat the seal well perpendicular and tap with a suitable tube or shim, never directly on the lip.

If you cannot find the code 9120 or need a neighboring size, the most practical thing is to send us the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we look for the equivalent in DBH or another brand we work with. You can also send us a photo of the part and the housing to confirm the design and avoid mounting errors.

At MR Accesorios Industriales we carry the DBH brand as part of our seals and oil seals catalog. If you want to request a quote for the DBH 9120 or ask about a similar size, write to us on WhatsApp with the code and the dimensions. We reply with the alternative that best fits your equipment.
