The DBH 8717Pol radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 31 mm shaft diameter, 50 mm housing diameter and 8 mm height, and an Lx-R-H design, it is press-fitted into the housing and runs on the shaft with a flexible lip. It is a key component in gearboxes, pumps and electric motors, where it prevents leaks and protects bearings. MR Accesorios Industriales supplies this official brand and advises you so you choose the correct seal.

This item is a radial shaft seal from the DBH line, identified by the code 8717Pol. Its dimensions are 31 mm shaft diameter (d), 50 mm housing diameter (D) and 8.00 mm height (h). The Lx-R-H design indicates a configuration with a sealing lip, reinforced body and retaining spring, suitable for applications requiring tightness against oils and greases. The exact designation lets you cross-reference the code with the manufacturer's data sheet and verify compatibility before installation.

Seals such as the 8717Pol are used in rotating equipment: gearboxes, centrifugal pumps, electric motors, spindles and belt or chain drives. Their function is twofold: retain lubricant inside the assembly and prevent the ingress of dust, water or particles that accelerate wear on bearings and bushings. In industrial environments with vibration or moderate temperature, a properly selected seal extends equipment service life and reduces maintenance downtime.

To install this seal, verify that the shaft has no burrs or marks that could damage the lip, and that the housing is clean and free of deformation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and place the seal perpendicular to the shaft, applying uniform pressure on the outer ring. If the shaft shows wear, consider an adjacent size or a seal with an auxiliary lip. Correct alignment and a shaft surface with adequate hardness are key to avoiding premature leaks.

If you need an equivalent or a different size, gather the data of the original seal: shaft diameter, housing diameter, height and design type. With that information, at MR Accesorios Industriales we can look for a compatible alternative within the brands we supply or suggest an adjacent size. You can also ask us about double-lip seals, special materials such as FKM or NBR, or high-temperature configurations. The idea is that you don't stop production for a sealing component.
