The DBH 6140 radial shaft seal is a lip seal that mounts on a 13 mm shaft and seals against a 26.05 mm housing, with a 9 mm height. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed housing.

This item is an Lx design oil seal, with the dimensions shown on its product page: shaft diameter 13 mm, housing diameter 26.05 mm and height 9.00 mm. The Lx design corresponds to a single-lip seal with a metal case and sealing lip, intended for rotating shafts with lubrication. It is a component of the seals and radial shaft seals category, and its commercial designation is 6140. Before mounting it, check that the shaft and housing have the indicated dimensions and that the contact surface is clean and free of burrs.

Typical applications for a seal of this size appear in equipment where the shaft diameter is small and the rotation speed is moderate: small electric motors, centrifugal pumps, gear reducers, compressors, machine tools and power transmission equipment. It is also found in agricultural implements and in process lines where oil or grease must be contained inside a housing. In all cases, the seal works alongside a bearing or bushing that needs clean lubricant free of external contamination.

To select the correct seal, in addition to the three dimensions you must take into account the type of lubricant, the working temperature and the shaft speed. The Lx design is suitable for rotating shafts with oil or grease lubrication, but if the equipment works with a lot of dirt or water, it is advisable to evaluate a seal with an auxiliary lip or dust guard. When mounting it, lubricate the lip before inserting it, seat the seal perpendicular to the shaft and avoid striking it on the sealing surface. If the shaft has a groove or wear, the seal may not seal even if the dimension is correct.

If you need a seal equivalent to the DBH 6140 or a nearby size, the most practical thing is to send us the full part number, the equipment brand and, if possible, the dimensions taken with a caliper: shaft diameter, housing diameter and height. With that data we can look for an alternative within the same radial shaft seal category or suggest a compatible replacement. It also helps if you tell us the type of lubricant and the working temperature, because that helps choose the lip material and the type of case.
