The DBH 5604 radial shaft seal is a lip seal designed to block the passage of lubricant and prevent contaminants from entering equipment with a rotating shaft. Due to its dimensions of 28.6 mm shaft, 50.8 mm housing and 11.11 mm height, with Mz design, it is used in gearboxes, pumps, electric motors and transmissions that need a reliable barrier against leaks and dust. MR Accesorios Industriales carries this official brand and advises you on choosing the right seal for your application.

This item is a DBH 5604 radial shaft seal, identified by the designation 5604 and part number 5604. Its main attributes are: shaft diameter 28.6 mm, housing diameter 50.8 mm and height 11.11 mm. The Mz design corresponds to a configuration with a sealing lip and metal case, suitable for retaining oil or grease on rotating shafts. These dimensions are what you must verify against the housing and shaft before installing it, because any difference in diameter or height prevents correct sealing.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases the seal's function is to keep lubricant inside the assembly and to block dust, water or particles that could damage the bearings. It is also used as a secondary seal in assemblies where a shaft rotates inside a fixed housing and an economical, easily replaceable barrier is needed.

To install a radial shaft seal, it is advisable to check the condition of the shaft and housing: there must be no burrs, scratches or wear that prevent uniform lip contact. The seal is inserted with a suitable installation tool, applying pressure on the outer ring and not on the lip, and the lip is lubricated with the same oil or grease used in the equipment before fitting it. If the shaft shows a groove or visible wear, consider a nearby size or a seal with the lip in a different position to avoid premature leaks.

With that data we can search the DBH line or other alternatives that share the shaft diameter, housing and height.
