The DBH 9439 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With 56 mm shaft diameter, 85 mm housing and 8 mm height, and Lx design, it is a common size in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales supplies it as an official brand within its seals and oil seals line.

This item is a DBH 9439 radial shaft seal, identified by its designation 9439. Its dimensions are 56 mm shaft diameter (d), 85 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. The DBH 9439 nomenclature allows it to be located without ambiguity against other sizes in the same family.

It is used in equipment where oil or grease must be contained at the point where the shaft passes through the housing: gearboxes, centrifugal pumps, electric motors, rollers and conveyors. It also appears in applications exposed to dust or splashes, where the sealing lip prevents contaminants from reaching the bearing or the lubricant.

For installation, check that the shaft and housing diameters match the indicated 56 mm and 85 mm, and that the housing width accommodates the 8.00 mm height. The shaft must be free of burrs or wear marks on the sealing track; it is advisable to lubricate the lip before inserting it and to use an installation tool that presses on the outer edge, never on the lip. If the shaft shows a groove, evaluate a nearby size or a seal with the lip in a different position.
