A radial shaft seal such as the DBH 9307 keeps oil or grease where it belongs: inside the housing, at the exact spot where a rotating shaft passes through. Gearboxes, pumps, electric motors and power transmission assemblies rely on this kind of lip seal to hold lubricant in and keep dust and water out. The code 9307 identifies the size — 18 mm shaft, 40 mm housing, 7 mm height — and the Lx designation describes how the lip is built.
Reading the code is the fastest way to confirm a match. The 9307 reference points to a seal for a shaft of 18 mm, a housing bore of 40 mm and an overall height of 7.00 mm. The Lx design means the sealing lip is rubber and has no metal spring behind it, which suits low fluid pressure and moderate shaft speed. DBH is one of the brands MR supplies.
You will find this seal on gearbox input and output shafts, centrifugal pumps, electric motors, rollers and other transmission components. Fan, mixer and conveyor shafts also use it, since escaping oil and incoming dust both shorten bearing life. In those positions the seal works together with the bearing and has a direct effect on how long the assembly lasts.
Correct fit matters more than anything else. Verify that the shaft and housing diameters match the published figures, that the shaft surface is ground and free of burrs, and that the bore is clean and undistorted. Lubricate the lip with the same oil or grease the equipment runs on before pressing it in. Shaft play or a worn journal prevents the lip from seating, and leakage typically shows up within hours of startup.
To quote part number 9307, send the shaft, housing and height dimensions. With those values we locate the matching reference in the seal and oil seal range. If the Lx design does not fit your operating conditions, we can point you to a lip with a spring or a double-lip option.
