The DBH 9321 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With a 17 mm shaft diameter, 45 mm housing and 7 mm height, and Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment to retain lubricant and stop the ingress of dust or water. MR Accesorios Industriales carries this brand and advises you on choosing the right size.

This item is a DBH 9321 radial shaft seal, identified by its designation 9321 and by the dimensions shown on the product page: shaft (d) 17 mm, housing (D) 45 mm and height (h) 7.00 mm. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The combination of dimensions defines the seat: the lip rests on the 17 mm shaft and the 45 mm outer diameter is press-fitted into the housing. It is a wear component that should be replaced at the first sign of leakage.

Typical applications for a seal of these dimensions appear in equipment with small-diameter shafts: electric motors, centrifugal pumps, gearboxes, reducers, compressors and machine tools. It is also found in agricultural implements and in power transmission equipment where the lubricant must be separated from the environment. In all cases it performs two functions: retaining the oil or grease of the bearing and preventing the entry of contaminants such as dust, chips or wash water.

To install it correctly, check that the 17 mm shaft has no burrs or wear on the sealing track and that the 45 mm housing is clean and free of dents. Lubricate the lip before inserting it and seat the part straight, without tilting it, using a tube or shim that rests on the outer diameter. The 7.00 mm height should sit flush or slightly recessed depending on the housing design. If the shaft shows a marked groove, consider a neighboring size or a repair sleeve.

If you cannot find part number 9321 or need an equivalent size, send us the equipment data: shaft diameter, housing diameter and housing height. With those three dimensions we look for the closest combination within the DBH line or another brand we carry. We can also check whether a seal with a different design is better suited when there is pressure, high peripheral speed or exposure to abrasive dust. The more complete the information, the faster the response.

MR Accesorios Industriales carries the DBH brand and has more than 80 years of experience in bearings, seals and power transmission.
