When a rotating shaft has to keep lubricant in and contaminants out, a radial shaft seal like the DBH 8998 does that job. Its Kx design covers the lip geometry and metal body, and its size suits gearboxes, pumps and mid-size transmissions. The three figures that matter are shaft 117.20 mm, housing 143.00 mm and width 12.70 mm. MR Industrial Accessories supplies this brand and helps you match the seal to the application.

The DBH 8998 belongs to the radial seals and oil seals family and carries the designation 8998. Read the size as bore fit first: d 117.2 mm for the shaft, D 143 mm for the housing seat, h 12.70 mm for the overall width. The Kx reference describes how the sealing lip and the metal case are shaped, so the part holds oil or grease against a shaft turning inside a cavity. Treated as a standard replacement item, it is ordered by that designation and those three dimensions.

You will find seals of this size in gearboxes, centrifugal pumps, large electric motors, conveyor rollers and power transmission assemblies. The task does not change from one to the next: retain the lubricant inside the bearing or gear area and keep dust, water and particles from reaching it. Fan shafts and industrial mixer shafts also use it as a secondary seal.

Correct installation starts with the shaft: no burrs, no wear at the contact zone. The housing seat should be clean and undeformed. Lubricate the lip before pushing the seal in, then seat it evenly rather than driving it with hammer blows. Selection depends on shaft speed, working temperature and the fluid being retained, since those factors decide whether the lip compound fits your equipment.

If the exact size is not what you need, or you want an equivalent, send part number 8998 or the measurements of the seal you are replacing. A compatible option can then be evaluated for your application. Shaft diameter, housing, height and lubricant type give the most accurate result.
