The DBH 6791 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It is an Mx design with a sealing lip and a metal case, sized for a 66.68 mm shaft, a 95.22 mm housing bore and a 15.87 mm height. The seal presses into the housing and runs against the shaft on a thin oil film, which provides the sealing action with low friction.

In this Mx design, the elastomeric lip is backed by a spring that keeps steady contact on the shaft. The metal outer case may carry a coating that helps it hold in the housing and compensate for small imperfections in the bore. The three critical dimensions to check are shaft 66.68 mm, housing 95.22 mm and width 15.87 mm.

Typical installations include gearboxes, pumps, electric motors, reducers and other power transmission equipment. The exclusion lip is useful where dust, water or chips are present, since it blocks particles from reaching the bearing area. Agricultural, road and process machinery often rely on this type of seal to prevent leaks and protect lubricant life.

Correct selection starts with matching the shaft and housing dimensions to the seal. The shaft surface should have the right hardness and roughness, and the housing bore must be clean and free of burrs. During installation, lubricate the lip with the same oil used in the equipment and press on the outer diameter with a proper tool, never on the lip. Keep the seal perpendicular to the shaft and avoid impacts.

If you need a seal with the same dimensions or a close variant, send the code 6791 or the dimensions by WhatsApp. The team can quote the DBH seal and suggest equivalents from other brands while keeping the shaft, housing and height dimensions unchanged. They can also help confirm that the Mx design fits your application.
