The DBH 8118 is a radial shaft seal that fits into the housing and runs against the rotating shaft to keep lubricant in and contaminants out. It measures 17 mm at the shaft, 28.50 mm at the housing and 6 mm in height, and uses the Lx lip profile. You will find this size in gear cases, pumps, electric motors and other power transmission equipment where bearings and gears need protection. MR supplies it as part of its seal line.

The code 8118 belongs to the DBH seal line. Reading the size: shaft 17 mm, housing 28.50 mm, height 6.00 mm. The Lx designation covers the lip shape and the outer body geometry. This is a single-lip radial seal for rotating shafts under permanent lubrication: the elastomer lip rides on the shaft while the rigid outer body presses into the housing bore. Confirm these figures against the original part before you install.

Seals in this size range show up on shafts up to 17 mm, for example small gear cases, centrifugal pumps, low-power motors, gearboxes, mixers and machine tools. In power transmission assemblies they also separate oil or grease from the surrounding environment. The job is always the same: hold the lubricant in, keep dust, water and particles out, and protect the bearings and gears behind the seal.

When selecting a replacement, match three values: shaft diameter, housing diameter and height. Inspect the shaft race as well; scratches, wear or burrs will prevent the lip from sealing, so repair or replace the shaft if needed. At installation, coat the lip with the same oil or grease used in the equipment, press the seal in squarely to the shaft and avoid impact. Because the Lx profile has a specific orientation, compare it with the old seal if that one had a different shape.

For an equivalent, send the code 8118 along with the shaft, housing and height dimensions. A photo of the original seal and the housing also speeds things up. With that information we can check the DBH line or another brand we carry and find the closest match.
