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 a 56 mm shaft diameter, 85 mm housing diameter and 8 mm height, and Lx design, it is a common size in gearboxes, pumps and transmission equipment. MR Accesorios Industriales sells it within its line of seals and oil seals.

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 makes it possible to locate it unambiguously 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 keeps contaminants from reaching the bearing or the lubricant.

To install it, check that the shaft diameter and housing diameter match the stated 56 mm and 85 mm, and that the housing width accommodates the 8.00 mm height. The shaft must be free of burrs and wear marks on the sealing surface; 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, consider a seal with the lip in a different position.
