The DBH 8218Pol oil seal is a radial shaft seal with 57 mm shaft diameter, 77 mm housing diameter and 10 mm height, with Lx-RAH design. It is used to retain lubricant and exclude contaminants in equipment with rotating shafts, such as gearboxes, pumps, electric motors and transmissions. Its flexible lip runs on the shaft and maintains sealing under continuous rotation. MR Accesorios Industriales carries this official brand and advises you to choose the correct size for your equipment.

This item is a DBH 8218Pol radial shaft seal, identified by its designation 8218Pol. Its dimensions are 57 mm shaft diameter (d), 77 mm housing diameter (D) and 10 mm height (h). The Lx-RAH design corresponds to a configuration with sealing lip and metal reinforcement, intended for mounting in a cylindrical housing. It is a direct replacement part: it is replaced by another with the same designation or by an equivalent that respects those three dimensions and the lip type.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases it fulfills two functions: retaining oil or grease inside the assembly and preventing the ingress of dust, water or particles. It is also used in machine tools and process equipment where the shaft rotates continuously and a reliable barrier is needed.

To select and install the seal, verify that the shaft diameter, housing diameter and height match the indicated values. The shaft surface must be clean, free of burrs and deep marks, and the housing must have the entry chamfer in good condition. Lubricate the lip before mounting and avoid hitting it during installation. If the shaft shows wear, evaluate a nearby size or a repair sleeve.

If you need an equivalent or a different size, send us the original code, the shaft and housing dimensions, and a photo of the part. With that data we can find the alternative that best fits your equipment. We can also advise you on design or material variants according to the fluid and working temperature. The idea is that you don't end up with the machine stopped for a seal you can't find.
