The DBH 5509 radial shaft seal is a lip seal designed to close off the passage of lubricant and prevent the entry of contaminants on rotating shafts. Its dimensions of 34 mm shaft diameter, 47 mm housing and a height of 9/10 mm make it suitable for gearboxes, pumps and medium-sized electric motors. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your equipment.

This item is a radial shaft seal from the DBH brand, identified with the code 5509. According to the record, 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 conditions of moderate dirt.

Typical applications of 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 in 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 as the equipment before inserting it and use an installation tube that rests on the outer diameter, never on the lip. The 9/10 mm height allows you to work with housings that have small variations. If the shaft shows wear, consider a neighboring size or a seal with a wear sleeve.

If you need an equivalent or a different size, the most practical thing is to send us the complete code engraved on the old seal, the equipment brand and a photo of the part. With that data we can search for alternatives within the same series or from other brands we carry. We can also quote a neighboring size if the housing or shaft have tolerances that allow another combination without modifying the machining.

To move forward with the quote, send the code 5509 or the SKU DBH-5509 by WhatsApp to MR Accesorios Industriales. Our technical team reviews alternatives right away. If you have doubts about installation or want to confirm that this seal is the one that corresponds to your equipment, attach a photo of the housing and the shaft. With more than 80 years in the sector, we help you resolve the replacement without hassle.
