The DBH 8152 is a radial shaft lip seal sized for a 40 mm shaft, an 80 mm housing bore and a 12 mm width. It keeps lubricant in and contaminants out at rotating shaft positions. The Lx design uses a single sealing lip with a metal outer case, which suits equipment with permanent lubrication running at moderate speed.

Reading the code helps when you compare it against what is installed. The 8152 designation belongs to the DBH seal line, and the three figures that matter for fit are shaft 40 mm, housing 80 mm and width 12 mm. The Lx configuration tells you the seal has one lip and a metal body, so the housing seat and the lip contact on the shaft are what define whether it drops in correctly.

You will find this size in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission components, as well as on fan, mixer and conveyor shafts. In those spots the seal holds oil or grease in place and blocks dust, water and particles that would otherwise reach the bearings and bushings. Before you specify it, confirm the shaft speed and the operating temperature at the sealing point.

Installation is straightforward if the surfaces are prepared first. Clean the housing bore and the shaft, remove burrs or marks that could cut the lip, and coat the seal with the same lubricant used in the equipment. Press it in squarely, without hammering the lip, until it seats fully. A shaft that is worn or grooved may call for a seal with an offset lip, and the final choice also depends on the lubricant type and the surrounding conditions.
