A rotary shaft lip seal, the DBH 8773 keeps lubricant where it belongs and keeps contaminants out of the bearing cavity. Its three governing measurements are 26 mm at the shaft, 34.50 mm at the housing bore and 5.50 mm in height, and it is built to the Lx-R profile. You will find seals of this type inside gearboxes, pumps, motors and other power transmission assemblies. MR Industrial Accessories supplies the DBH line and can cross-check your measurements or point you to an equivalent.

The 8773 carries the DBH brand and belongs to the radial shaft seal family. Read the size string in the usual order: the first figure is the shaft the lip rides on, the second is the bore it presses into, and the third is the overall height. Here that gives shaft 26 mm, housing 34.50 mm and width 5.50 mm. The Lx-R designation covers the shape of the sealing lip together with the outer casing profile. An elastomer lip does the sealing against the rotating shaft, a metal case holds the shape and provides the interference fit, and the compound is chosen to stand up to oils and greases.

Equipment that relies on a seal in this size range includes gear reducers, centrifugal pumps, electric motors, compressors, mixers and machine tools. The same duty shows up on conveyor rollers and throughout power transmission drives, wherever oil has to stay in and grit has to stay out so the bearings survive. Before anything goes back together, look over the shaft for scoring, burrs or a worn lip track, and check that the housing bore is clean and still round.

Choosing a replacement starts with matching all three dimensions; a seal that is right on two of them will not seat or will not seal. Beyond size, weigh the lubricant in use, the operating temperature, how fast the shaft turns and whether dust or water is present. Lx-R describes one specific lip and outer geometry, so if the part you removed looks different, compare it against a drawing or the old sample. A lip fitted backwards, or a bore that has been damaged during removal, will leak no matter how accurate the dimensions are. Seat the seal squarely with a proper driver and put a film of lubricant on the lip first.

If you are hunting an equivalent for the 8773, send the full part number, the three measurements and a photo of the old seal. That is enough for us to search the radial seal range for a match or a workable substitute, and to tell you whether the Lx-R geometry lines up with what came out of your machine. The more detail you provide, the fewer rounds it takes to land on the right part.

Send the part number for the DBH 8773 by WhatsApp or email to MR Industrial Accessories and the team will come back to you promptly. Questions about fitment or about the Lx-R profile are welcome as well, and we can suggest equivalents when the original is not the best route.
