The DBH 8551Pol oil seal is a single-lip radial seal with a spring, designed for rotating shafts. Its function is to retain the lubricant inside the housing and prevent the ingress of dust, water or contaminating particles. It is press-fitted into the housing and runs on the shaft with an oil film that guarantees sealing and low friction. It is a key part in pumps, electric motors, gear reducer boxes and transmission equipment, where reliable sealing extends the service life of bearings and gears.

This DBH 8551Pol seal has a shaft diameter of 58 mm, a housing diameter of 75 mm and a height of 9 mm. Its Lx-R design combines a spring-loaded sealing lip and an outer elastomer cover, which facilitates mounting and improves sealing in housings with standard tolerances. The 8551Pol designation identifies the geometry and lip material, suitable for applications with mineral oils and moderate temperatures.

Typical applications include centrifugal pumps, electric motors, speed reducers, transmission shafts and process equipment. In all cases, the seal protects bearings and gears from premature wear due to contamination. It is also used in agricultural and industrial machinery where efficient sealing is required in reduced spaces.

To select it correctly, verify that the shaft and housing dimensions match those indicated. The shaft must have adequate surface hardness and controlled roughness to prevent leaks. During mounting, lubricate the lip with the same oil used in the equipment and make sure the spring is correctly positioned. Avoid striking the seal and verify the concentricity of the housing.
