The DBH 6731Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles. With dimensions of 120 mm shaft diameter, 145 mm housing bore and 15 mm height, and a Kx design, it adapts to equipment where axial space is limited. It is a common replacement part in pumps, electric motors and gearboxes. At MR Accesorios Industriales you can request a quote for it on WhatsApp.

This DBH 6731Pol seal has a shaft diameter of 120 mm, a housing bore diameter of 145 mm and a height of 15.00 mm. The Kx design corresponds to a seal with a sealing lip and a profile that usually includes a secondary exclusion lip. The designation 6731Pol identifies the size and construction type within the DBH line. It is a radial sealing component for rotating shafts, not for linear motion or for high pressures. It is press-fitted into the housing and runs on the shaft surface.

Typical applications for a seal of these dimensions include centrifugal pumps, medium-sized electric motors, reducers and gearboxes, and power transmission equipment in general. In these assemblies, the seal prevents oil or grease leaks and protects the bearings from contaminant ingress. It is also used in agricultural machinery, process equipment and pumping systems where the shaft rotates at moderate speeds and the working temperature is that of a standard industrial lubricant.

To select this seal correctly, check that the shaft and housing dimensions match those of the equipment. The shaft surface must be ground, free of splines or wear, and the housing must have the appropriate diameter and depth. During installation, lubricate the lip with the same oil or grease as the equipment, insert the seal perpendicularly and avoid striking the lip. If the shaft has a groove or wear, consider a nearby size or a seal with the lip in another position.
