The DBH 5509 is a radial shaft seal built to retain lubricant and block contaminants on rotating shafts. With a 34 mm shaft diameter, 47 mm housing diameter, and 9/10 mm height, it fits gearboxes, pumps, and mid-size electric motors. MR supplies this seal and helps you select the right one for your equipment.

This seal carries the DBH brand and the code 5509. It follows an Mx design, which often includes an auxiliary lip or a configuration that improves sealing in moderately dirty environments. The height of 9/10 mm means the seal can accommodate housings with minor dimensional variations within that range.

Common uses include gearboxes, centrifugal pumps, electric motors, reducers, and other power transmission equipment. The seal keeps oil or grease inside the assembly while keeping out dust, water, and particles that could damage bearings. It is a wear component that should be replaced when leaks or unusual noises appear near the seal.

For correct installation, make sure the shaft is free of burrs or marks that could cut the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and press only on the outer diameter with an installation tube. The 9/10 mm height accommodates small housing variations. If the shaft is worn, consider a seal with a wear sleeve.
