The DBH 8522Pol is a single-lip radial shaft seal used to hold lubricant in and keep contaminants out of rotating equipment. Its Lx-R-H layout pairs a main sealing lip with a reinforced body and a secondary lip that shields the sealing zone. The size is given as 65 mm for the shaft, 95 mm for the housing bore and 14.00 mm for the height, which makes it a frequent replacement item on gearboxes, pumps and transmission units. MR supplies this brand and can help you confirm the right seal for the job.

Reading the designation: 8522Pol is the reference, and Lx-R-H describes the build. One lip does the sealing against the rotating shaft, a metal reinforcement gives the body its shape and rigidity, and an auxiliary lip sits outboard to block dust and splashes. The three key figures to match are shaft 65 mm, housing 95 mm and height 14.00 mm. Equipment built around a 65 mm shaft is where this seal most often comes up as a service part.

Gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission assemblies are the usual homes for a seal of this type. In each case it works on two fronts at once: it keeps the oil or grease where it belongs, and it stops outside particles from reaching the bearing or shaft, where they would speed up wear. The size points to medium-sized industrial machinery such as conveyors, mixers and machine tools.

Selection comes down to three measurements plus the condition of the shaft. Confirm that shaft, housing and height match your equipment, then inspect the shaft surface: it should be clean, without burrs or deep scoring, and with hardness and roughness that suit the lip. During installation, coat the lip with the same oil or grease the equipment runs on, seat the seal square to the shaft and avoid hammering it. If the bore itself is worn, look at repairing it or using a seal with a sleeve.

If you need an alternative to 8522Pol, we can look for one. Send the original code, the shaft, housing and height dimensions, and a photo of the old seal if you have one, by WhatsApp or email. Our team checks the brands we supply and comes back with the option that fits your equipment.

This DBH seal is one of the brands we supply, so compatibility questions are welcome. Proper fitting and routine checks are what keep a seal working and the internals of the machine protected. If the size or the lip type is unclear, message us and we will help you pin down the part.
