The DBH 5407 is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns inside a housing. Its size — shaft 27 mm, housing 44.40 mm, height 9.52 mm — fits assemblies where room around the shaft is tight. You will find this seal in pumps, motors, gearboxes and transmission units that depend on a dependable barrier against leakage.
This seal carries the DBH brand and the code 5407. Reading the size: d, the shaft diameter, is 27 mm; D, the housing bore, is 44.40 mm; h, the height, is 9.52 mm. The Lx design means one lip with a spring, which keeps oil or grease contained during continuous rotation. The lip rides against the shaft while the outer case presses into the housing bore to close the gap.
Where does it show up? Centrifugal pumps, electric motors, speed reducers, transmission shafts and process equipment are common hosts. In each case the seal stops lubricant from escaping and shields bearings and gears from dust, moisture and outside particles. Treat it as a wear item: leaks, unusual noise or shaft movement are signals that it is time to replace it.
Installation matters as much as the part. Check the shaft for burrs or grooves and confirm the housing bore is clean and undistorted. Coat the lip with the same oil or grease the equipment runs on, then press the seal in with a proper mounting tube, keeping it square to the shaft. Do not hit the lip or the spring. If the shaft shows a wear groove, a repair sleeve or a different size may be the better route.
