The DBH 8874 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain oil or grease and block the entry of dust and water. Its dimensions of 20 mm shaft diameter, 38 mm housing diameter and 8 mm height make it suitable for gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified by part number 8874. Its dimensions are 20.00 mm shaft diameter (d), 38.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a seal with a single sealing lip and spring, intended for rotating shafts with permanent lubrication. The DBH 8874 nomenclature makes it easy to locate in catalogs and replenishment systems.

It is used in equipment with rotating motion where lubricant must be contained: gearboxes, centrifugal pumps, electric motors, compressors, mixers and conveyor rollers. It also appears in automotive and agricultural machinery applications. Its main function is to prevent oil or grease leaks and, at the same time, stop contaminating particles from entering that accelerate wear on bearings and gears.

For correct installation, check that the shaft has the right hardness and surface finish, with no burrs or marks that could damage the lip. Lubricate the seal before installing it and use an installation tube that presses on the outer diameter, never on the lip. Selection depends on rotation speed, working temperature and the type of fluid. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip.
