The DBH 8529Pol is a radial shaft seal that keeps lubricant where it belongs and keeps dust, water and other contaminants out of rotating equipment. It fits a 40 mm shaft, a 52 mm housing bore and a 6.00 mm height, and it presses into the housing or cover. Because the lip wears over time, the seal is replaced whenever oil starts seeping out or dirt works its way in. MR Industrial Accessories LLC supplies this brand to customers throughout the United States and Latin America.

Reading the code helps you confirm you have the right part. The designation is 8529Pol, and the Lx-R-H configuration tells you what you are holding: a sealing lip, a reinforced body and a retaining spring. The elastomer lip rides against the rotating shaft, the spring holds steady pressure on that lip, and the metal outer case locks the seal into the bore. Shaft 40 mm, housing 52 mm, height 6.00 mm. Seals like this show up wherever a shaft turns and lubricant has to stay contained.

You will find this seal in gearboxes, pumps, electric motors, reducers and transmission shafts, as well as in process equipment, conveyors, machine tools and hydraulic systems. Automotive and agricultural machinery use the same style of seal. When it fails, oil escapes and contaminants enter, which speeds up wear on bearings and gears. Treating replacement as part of scheduled preventive maintenance is the practical way to protect those components.

Selection comes down to matching three measurements: shaft, housing and height. Confirm the Lx-R-H design also suits the lubricant in use and the temperature and speed of the application. At installation, coat the lip with the same oil or grease the equipment runs on, then seat the seal squarely so the lip is not damaged. A shaft with wear or a rough finish should be restored or replaced, and cleaning the housing beforehand prevents leaks.
