When a rotating shaft passes through a housing, the DBH 9727 seal keeps lubricant in and contaminants out. It is a single-lip radial shaft seal built to the Kx design, which means a spring-loaded lip that stays in contact with the shaft. MR Industrial Accessories LLC supplies this brand and helps maintenance and purchasing teams confirm the right seal for the job.

The code 9727 identifies this DBH seal, and the numbers behind it describe the fit: shaft 38.10 mm, housing 50.30 mm, width 11.10 mm. Those three values are what you compare against the seal you are removing from a pump, motor, gearbox or bearing position. The Kx designation tells you the lip carries a spring, so contact on the shaft is maintained as the seal runs.

You will find this type of seal anywhere a shaft turns inside a housing and the oil side has to stay separate from the outside: centrifugal pumps, electric motors, gear reducers, mixers, conveyors, agricultural and industrial machinery, and the bearing positions of split plummer block housings, as long as the shaft and housing measure as noted above.

Installation is straightforward but the shaft condition matters. Clean the shaft and remove burrs or marks, check that the housing bore is round and undamaged, and coat the lip with the same oil or grease the equipment uses before you seat the seal. The Kx lip performs best at moderate peripheral speeds and needs a shaft surface with the right hardness and finish; if the shaft is worn, a repair sleeve is worth considering before you press in a new seal.

If you are sourcing a replacement, the code 9727 or the three dimensions from your original seal are enough to start. Send them and we check the DBH line plus other compatible options. If a shaft or housing has been reground, we can also look at the same seal type in a different size. No data sheet is required from your side.
