Part of the DBH seal range, the 9565 is a radial shaft seal built for rotating shafts. It measures 40 mm at the shaft, 55 mm at the housing bore and 7 mm in height. Installed by press fit into the housing, it keeps lubricant where it belongs while keeping dust, water and particles out, which is what protects the bearings and bushings around it. How well the shaft and bore surfaces are finished has a direct effect on how long the lip lasts. Pumps, electric motors and gearboxes are the usual places you find this size.

The code 9565 covers one fixed combination of dimensions: 40 mm shaft, 55 mm bore, 7 mm height. The Lx design tells you what you are holding: one sealing lip, an outer metal case, made for pressing into a cylindrical bore. Because the number stands for that dimension set, any cross-reference work has to begin with those three figures matching exactly.

You will see a seal this size in centrifugal pumps, electric motors in the low to medium power range, speed reducers, transmission shafts and other process equipment with rotating shafts. In each case it does two jobs at once, holding oil or grease in and blocking contaminants from getting in. Machine tools, conveyors and food industry equipment also use it, since a clean working environment matters there.

Checking a seal before ordering means confirming three things: shaft diameter, bore diameter and the depth you have to work with. The shaft should be ground and free of burrs, since a rough finish will wear the lip early. A chamfer at the bore entry helps the lip slide in without damage. Put some lubricant on the lip first, and drive the seal with a tube that presses on the metal case instead of the lip.

If you want an equivalent from another brand, send us code 9565 together with the shaft, bore and height measurements taken from the equipment. With that information we can check alternatives within the DBH line or from other brands we carry. Tell us as well if the original part has a special geometry, such as a second lip or an extra spring, so the replacement matches what the application needs.

DBH is one of the seal brands we supply at MR Industrial Accessories. If you already have code 9565 or the 40 x 55 x 7 mm dimensions, message us on WhatsApp with the details and we will quote it. We can also help with seals in other sizes or with any other sealing component your maintenance work calls for.
