The DBH 5972 radial shaft seal is a lip seal designed to block the passage of oil or grease on rotating shafts and protect against the ingress of dust and water. With dimensions of 50.80 mm shaft, 76.12 mm housing and 12.70 mm height, it is press-fitted into crankcases, gearboxes and pumps. Its Mz design combines a main lip with a secondary exclusion lip, making it suitable for environments with moderate dirt.

This DBH 5972 seal has a shaft diameter of 50.80 mm, a housing diameter of 76.12 mm and a height of 12.70 mm. The Mz design indicates that it has a main sealing lip and a secondary exclusion lip, mounted on a metal body that fits into the housing. The exclusion lip helps retain lubricant and slows the ingress of external contaminants, while the main lip works on the shaft to prevent leaks. It is a common replacement component in equipment with rotating shafts.

It is used in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment in general. It also appears in agricultural machinery, conveyors and chain or belt drive systems where bearings and gears must be protected. As an inch dimension converted to millimeters, it is common in imported equipment or lines of US origin. If the seal works in a very dusty environment, the exclusion lip of the Mz design provides an additional barrier that extends seal life.

To select the correct seal, verify that the three dimensions match the shaft, housing and available depth. The shaft surface must be ground and free of grooves; excessive roughness wears the lip prematurely. When installing, lubricate the lip with the same grease or oil used in the equipment, insert it perpendicular to the shaft and tap on the outer edge with a suitable tube or driver, never on the lip. If the housing has burrs, clean them before fitting the seal to avoid damaging the metal body.
