The DBH 6140 is a radial shaft seal, also called an oil seal, sized for a 13 mm shaft, a 26.05 mm housing bore and a 9 mm width. Its job is to keep lubricant where it belongs and to block dust, water and other contaminants from reaching the bearings and bushings inside the assembly. You will find seals like this in gearboxes, pumps, motors and other power transmission equipment where a rotating shaft passes through a fixed housing.

This seal uses the Lx design: a single sealing lip with a metal case, made for rotating shafts that run with oil or grease. The commercial designation is 6140. The three dimensions you need to confirm before ordering are shaft 13 mm, housing 26.05 mm and width 9.00 mm. Check the shaft and bore against those figures, and make sure the contact surface is clean and free of burrs.

Seals in this size range turn up in small electric motors, centrifugal pumps, gear reducers, compressors, machine tools and similar power transmission equipment, as well as in agricultural implements and process lines where oil or grease has to stay inside a housing. In every case the seal works together with a bearing or bushing that needs clean lubricant and no outside contamination.

Choosing the right seal means looking beyond the three dimensions. Lubricant type, operating temperature and shaft speed all matter. The Lx design fits rotating shafts with oil or grease lubrication, but in equipment exposed to heavy dirt or water, a seal with an auxiliary lip or dust guard is worth considering. During installation, lubricate the lip first, press the seal in perpendicular to the shaft and avoid hitting the sealing surface. A groove or worn area on the shaft can prevent sealing even when the dimensions are correct.

If you are looking for an equivalent to the DBH 6140, send the full part number, the equipment brand and, if you can, caliper readings for shaft diameter, housing bore and width. With that information we can search for an alternative in the same radial shaft seal category or propose a compatible replacement. Telling us the lubricant type and working temperature also helps, since those influence the lip material and case style.
