The DBH 9621 is a radial shaft seal that sits in the housing and works against a rotating shaft. It keeps lubricant in and keeps dust, water and other particles out. With a 40 mm shaft, a 53 mm housing and design A 260, it is found in gearboxes, pumps, electric motors and transmission equipment. MR Industrial Accessories supplies this seal and can quote it for you.

This part is identified as DBH 9621. In the size code, 40 mm is the shaft diameter (d), 53 mm is the housing bore (D) and 0 mm is the height (h); the design is A 260. Those values describe a single-lip seal for rotating shafts where oil or grease must be retained and contaminants kept out. Design A 260 refers to a specific mounting geometry, so it is worth checking the manufacturer's data sheet before you replace the old seal.

Seals in this size range commonly appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In each case the seal runs on a rotating shaft and separates a lubricated side from an exposed side. You will also find them in machine tools and process equipment, where the aim is to stop leaks and protect the bearing or bushing in the same assembly.

For a correct installation, make sure the shaft is clean, free of burrs and lightly lubricated. The seal should go into the housing squarely, without hammer blows that could distort the lip. If the shaft shows wear, a seal with an extra lip may be worth considering. Speed, temperature and the fluid being sealed all affect the choice, so confirm that design A 260 fits your case before ordering.

If you need an equivalent, send the code 9621 along with the shaft, housing and height dimensions, plus the fluid type and operating temperature. With that information we can look for a replacement in the same radial shaft seal category. You can also ask about other brands or a seal with special features if your installation calls for it.
