The DBH 5276 radial shaft seal is a lip seal that mounts in cylindrical housings to retain lubricant and block contaminants from entering rotating shafts. With dimensions of 50 mm shaft diameter, 90 mm housing diameter and 10 mm height, and an Lx design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales carries it as part of its line of seals and oil seals for industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified by part number 5276. Its standard dimensions are 50 mm shaft diameter (d), 90 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip configuration with spring, intended for rotating shafts with lubrication. The lip elastomer and the metal body work together to maintain sealing under continuous rotation conditions.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors and power transmission equipment. In all cases, the function is the same: prevent oil or grease leaks and protect bearings and gears from dust, water or particles that could accelerate wear. It is a preventive maintenance part that should be replaced when leaks or abnormal noises are detected.

To install the seal correctly, verify that the shaft has adequate hardness and surface finish, with no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it into the housing, and use an installation tube that presses on the outer ring, never on the lip. The 10 mm height and 90 mm diameter must match the housing to ensure a firm, centered fit.
