The DBH 5509 radial shaft seal is a lip seal designed to stop lubricant from escaping and keep contaminants out of rotating shafts. Its dimensions of 34 mm shaft diameter, 47 mm housing diameter and 9/10 mm height make it suitable for gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales sells this brand and advises you so you choose the right seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified by code 5509. It corresponds to an Mx design and its dimensions are: shaft diameter (d) 34 mm, housing diameter (D) 47 mm and height (h) 9/10 mm. That variable height indicates that the lip or the body of the seal can adapt to housings with dimensional tolerances within that range. The Mx design usually includes an auxiliary lip or a specific configuration to improve sealing under moderate dirt conditions.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases, the function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings. It is a wear part that should be replaced when leaks or abnormal noises appear around the seal area.

To correctly install a radial shaft seal, check that the shaft has no 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 use an installation tube that presses on the outer diameter, never on the lip. The 9/10 mm height lets you work with housings that have small variations. If the shaft shows wear, consider a seal with a wear sleeve.

If you need an equivalent or a different size, the most practical thing is to send us the full code stamped on the old seal, the equipment brand and a photo of the part. With that data we can look for alternatives within the same series or from other brands we sell.
