When a rotating shaft needs its lubricant kept in and outside contamination kept out, the DBH 8591Pol lip seal is built for that job. It fits a 72 mm shaft inside a 94 mm housing bore with a 12 mm height, and it follows the Lx-R design. Gearboxes, pumps, motors and similar transmission assemblies are where this size shows up most often. MR Industrial Accessories supplies this brand and helps you match the seal to your equipment.

Reading the 8591Pol designation starts with the numbers printed on the seal itself. The published figures are shaft 72 mm, housing 94 mm and height 12.00 mm, with Lx-R as the design code. Lx-R indicates a sealing lip combined with a spring, which suits rotating shafts that run with lubrication. Check each of those three measurements against the shaft and the bore before you install anything, because a mismatch on shaft diameter or housing depth changes how the lip sits.

You will find seals of this size in gearboxes and reducers, centrifugal pumps, electric motors, rollers and power transmission drives. Two jobs are done at once in those spots: oil or grease stays where it belongs, and dust, water and particles are kept from working their way in. Fan, mixer and conveyor shafts in dusty or damp conditions are another common place for this seal.

Installation results depend heavily on shaft condition. Look for burrs, scratches or wear across the area where the lip makes contact, and make sure the housing is clean and not deformed. Put a light film of lubricant on the lip before pressing the seal in, with the lip turned toward the fluid you are containing. A visible groove or heavy wear on the shaft is a signal to consider a seal with the lip set in a different position or a repair size.

Need a substitute? Send the 8591Pol number along with your shaft and housing measurements, the fluid involved and the operating temperature. That information lets us search the DBH line or another brand we carry for a match. If the seal sits in an assembly with bearings or housings, tell us, so the choice stays consistent with the rest of the system.
