The DBH 8517Pol is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a housing. It measures 80 mm at the shaft, 105 mm at the housing bore and 10.00 mm in height, and its Lx-R design uses a single lip with a spring. Maintenance teams reach for this seal when rebuilding gearboxes, pumps and other power transmission equipment, and it sits in the seals and oil seals range that MR Industrial Accessories supplies.

The designation 8517Pol identifies the size and style within the DBH line. Reading it alongside the dimensions makes selection straightforward: shaft 80 mm, housing 105 mm, width 10.00 mm. The Lx-R configuration is a spring-loaded single lip built for rotating shafts that run with oil or grease. Because DBH is one of the brands MR carries, the seal fits the current catalog and can be quoted by code alone.

You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and similar power transmission assemblies. Its job is always the same: hold the lubricant where it belongs and keep dust, water and particles away from bearings and gears. Treat it as a wear item. Once oil weeps past the lip or the area starts making unusual noise, plan the replacement before the bearing suffers.

Installation rewards a little care. Confirm the shaft is at 80 mm and the bore at 105 mm, and check both surfaces for burrs, nicks or corrosion. Coat the lip with the lubricant it will see in service, then seat the seal with the lip facing the fluid side. The 10.00 mm height should sit flush or slightly recessed, depending on how the housing is machined. A grooved or worn shaft is best handled with a repair sleeve rather than a new seal alone.

If you are matching a seal already in service, send the code 8517Pol or the measured shaft and housing dimensions. The team can search the seals category for equivalents that keep the Lx-R design and the critical dimensions intact. Details such as equipment type, the fluid being sealed and operating conditions help narrow the options and avoid a second teardown.
