The DBH 1209 is a radial shaft seal with a single lip, built to keep oil or grease where it belongs inside equipment that turns on a rotating shaft. Its three key measurements are a 47.6 mm shaft, a 69.85 mm housing bore and a 9.50 mm height, which puts it in the medium size range for industrial maintenance work. MR Industrial Accessories supplies this seal to plants and workshops throughout the United States and to several countries in Latin America.

The code describes the geometry: shaft 47.6 mm, housing 69.85 mm, width 9.50 mm. The Lx designation identifies a single-lip seal with a spring, the usual choice for rotating shafts that run with permanent lubrication. The outer case is metal, and the lip does the sealing against the shaft surface.

Before ordering, confirm three points. The shaft must measure 47.6 mm within the tolerance your equipment calls for. The bore must be 69.85 mm and deep enough to take the full 9.50 mm height without pressing on the lip. The lip compound also has to suit the fluid in the sump and the temperature the seal will see in service.

These dimensions turn up in gearboxes, centrifugal pumps, electric motors, mixers and power transmission assemblies, as well as on fan and conveyor shafts in dusty or wet areas. In each case the job is the same: hold the lubricant in and keep dust, water and particles out, so bearings and gears are not worn down ahead of schedule.

Installation decides how long the seal lasts. Work on a clean shaft with no burrs or scoring, lubricate the lip before sliding it into place, and seat it square to the bore. A cocked seal or a grooved shaft will leak even when the part is new.

If you are cross-referencing a different make, send the full code stamped on the old seal, the three dimensions, and a photo of the removed part. From that we can propose an equivalent in the same category or point you to another option. We can also tell you whether the Lx design is the right fit for your equipment.
