The DBH 8186Pol oil seal is a radial seal with a 45.00 mm shaft diameter, 65.00 mm housing diameter and 9.00 mm height, with an Mx-Hel design. It is used to retain lubricant and exclude contaminants in rotating equipment, protecting bearings and guides. It is a wear part that should be replaced when oil leakage or dust ingress appears. MR Accesorios Industriales carries this brand and advises you on choosing the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified as 8186Pol. Its dimensions are 45.00 mm shaft diameter (d), 65.00 mm housing diameter (D) and 9.00 mm height (h). The Mx-Hel design corresponds to a lip with a spring and a helical configuration, intended for applications with continuous rotation and the presence of oil or grease. The designation 8186Pol makes it easy to locate in the catalog and compare it with other alternatives in the same family.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment with lubricated bearings. In industrial plants it is found sealing shaft ends on conveyors, mixers and machine tools. Its function is twofold: to prevent lubricant leaks to the outside and to block the entry of dust, water or particles that accelerate bearing wear.

To install it correctly, verify that the shaft has no burrs or deep marks and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal with a flat tool that presses on the outer diameter, never on the lip. Shaft runout and housing alignment affect service life. If the equipment operates with heavy vibration or temperature, contact us and we will evaluate an alternative design.

If you need a nearby size or an equivalent, send us the code 8186Pol, the shaft, housing and height dimensions, and a photo of the old seal. A drawing or the equipment data sheet also works. With that data we look for the option available in the DBH line or in another brand we carry, respecting the Mx-Hel design when necessary. You don't need to have everything perfect: with the code and an approximate measurement we can already guide you.
