The DBH 5208 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and moisture from entering equipment with rotating shafts. Its Lz-R design combines a sealing lip with a protective outer lip, making it suitable for environments with moderate dirt. It is press-fitted into cylindrical housings and runs on 40 mm shafts, with a 60 mm outer diameter and 10 mm height. It is a frequently replaced part in pumps, electric motors and gearboxes.

This DBH 5208 oil seal has a shaft diameter of 40 mm, a housing diameter of 60 mm and a height of 10 mm. The Lz-R design indicates a configuration with a sealing lip and an outer lip, designed to retain lubricant and repel particles. The 5208 designation corresponds to the single-wall radial shaft seal series, with elastomer and steel spring. It is press-fitted into the housing and the lip rests on the rotating shaft, creating a dynamic seal.

It is used in centrifugal pumps, electric motors, gearboxes, drive shafts and process equipment. It also appears in machine tools, agitators and conveyors, where the shaft rotates and lubricant must be contained. In environments with dust or chips, the outer lip of the Lz-R design provides an additional barrier. It is a wear part: it should be checked at every preventive maintenance interval and replaced if it shows cuts, hardening or loss of elasticity.

To install it, verify that the shaft is clean, free of burrs and scratches, and that the sealing surface is not worn. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The housing must be machined with the proper tolerance and without steps. Tap evenly with a tube or driver that rests on the outer ring, never on the lip. If the shaft shows a deep groove, consider a nearby size or a wear sleeve.
