The DBH 5561 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of dust, water or particles. With dimensions of 28 mm shaft diameter, 40 mm housing and 7 mm height, and an Lz design, it is used in pumps, electric motors, gearboxes and industrial equipment in general. MR Accesorios Industriales carries this official brand and advises you so you can choose the correct oil seal for your application.

This item is a radial shaft seal from the DBH brand, identified by code 5561. Its standard dimensions are: shaft diameter (d) 28 mm, housing diameter (D) 40 mm and height (h) 7.00 mm. The Lz design indicates a configuration with a sealing lip and a specific profile that allows it to adapt to rotating shafts with lubrication. It is manufactured with elastomers resistant to oil and wear, and its structure includes a spring that keeps the lip in constant contact with the shaft to ensure sealing.

Typical applications of this oil seal include centrifugal pumps, electric motors, speed reducers, compressors, machine tools and transmission equipment. In all these cases, the 5561 oil seal protects bearings and gears from external contamination and prevents oil or grease leaks. It is a critical part in industrial maintenance, since its failure can cause unscheduled downtime and costly damage to internal components.

For installation, verify that the shaft has adequate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the seal lip before installing it and make sure the orientation is correct: the lip must face the fluid to be retained. When selecting an oil seal, consider the rotation speed, working temperature and chemical compatibility of the elastomer with the lubricant.
