The DBH 8186Pol is a radial shaft seal built to hold lubricant in and keep contaminants out of rotating equipment. Its Mx-Hel lip design suits continuous rotation where oil or grease is present. Because it is a wear part, leakage or dirt ingress at the shaft is the usual sign that a replacement is due. MR supplies this seal and can help you confirm the right choice for your machine.

Reading the code helps when you compare options. The 8186Pol belongs to the DBH line, and its size is given as shaft 45.00 mm, housing 65.00 mm, height 9.00 mm. The Mx-Hel lip runs with a spring and a helical profile. These three measurements are what you match against the seal currently fitted.

Seals in this size range turn up on gearboxes, centrifugal pumps, electric motors, transmission shafts and other lubricated assemblies. In plants you will also find them at shaft ends on conveyors, mixers and machine tools. The job is the same in each case: keep oil where it belongs and stop dust, water and particles from reaching the bearings.

Fitting matters as much as the part. Check the shaft for burrs or deep marks and make sure the housing seat is clean and undistorted. Apply lubricant to the lip, then press the seal in with a flat driver that contacts the outer diameter only, never the lip. Shaft runout and housing alignment both affect how long the seal lasts. If the equipment runs with strong vibration or high temperature, tell us and we will look at another design.

When you ask for a quote on 8186Pol, include the shaft, housing and height measurements and a photo of the old seal if you have one. A drawing or the equipment data sheet works too. With that information we check what is available in the DBH line or in another brand we carry, keeping the Mx-Hel design where the application calls for it. Approximate measurements are fine to start with.
