MR Accesorios Industriales sells this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 8644. Its standard dimensions are: shaft diameter (d) 38 mm, housing diameter (D) 47 mm and height (h) 10 mm. The Mz design corresponds to a configuration with a single sealing lip and spring, suitable for rotating shafts with lubrication. The lip elastomer and the metal body are designed to withstand the usual working conditions in industrial equipment, provided they are mounted on ground surfaces free of burrs.

Typical applications for this seal include gearboxes, speed reducers, centrifugal pumps, electric motors and transmission equipment. In all cases, its function is to confine the oil or grease inside the bearing or chamber, and to block the passage of external contaminants. It is a wear part that should be replaced when leaks or abnormal noises are detected, or during a major repair of the equipment. It is also used in machine tools and continuous process equipment.

To correctly select a seal, check that the shaft and housing dimensions match those of your equipment's housing and shaft. The height must be compatible with the housing depth. The Mz design is appropriate for rotating shafts with moderate peripheral speeds and adequate lubrication. During mounting, lubricate the lip with the same oil used in the equipment, insert it perpendicularly and avoid striking it. If the shaft shows wear, consider using a wear sleeve or consult our technical team.
