The DBH 5511 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. With dimensions of 30 mm shaft, 47 mm housing and 10/12 mm height, it is press-fitted into covers, gearboxes and motors. MR Accesorios Industriales carries this official brand so you have a reliable alternative for your maintenance work.

This item is a DBH 5511 radial shaft seal. According to its designation and attributes, it has a shaft diameter of 30 mm, a housing diameter of 47 mm and a height of 10.00/12.00 mm. The Mx design indicates a configuration with a sealing lip and metal body, suitable for rotating shafts. The variable height allows the seal to adapt to housings with different mounting depths, keeping the lip in contact with the track. It is a common replacement part in equipment where there is rotary motion and a need for sealing.

Typical applications of this seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. In industry, it is found sealing output shafts, input shafts and points where lubricant must remain confined. It is also used in agricultural machinery, conveying equipment and hydraulic systems. Its function is critical to prevent leaks and contamination, extending the service life of bearings and gears. It is a wear component that should be replaced at every major intervention.

To correctly mount a radial shaft seal, verify that the shaft has no burrs or excessive wear in the contact area. Lubricate the lip with the same oil or grease as the equipment before inserting it. Place the seal perpendicular to the shaft, using a mounting tube that rests on the outer diameter, never on the lip. If the housing is damaged, consider repairing it or using a seal with a larger outer diameter. Selection must consider speed, temperature and type of fluid. If in doubt, consult our technical team.

If you need an equivalent seal or a nearby size, the most practical thing is to send us the code engraved on the part or the dimensions taken with a caliper: shaft diameter, housing diameter and height. With that data we can look for alternatives in other brands or series that perform the same function. We can also advise you if the Mx design is not suitable for your application. At MR Accesorios Industriales we have experience in seals and oil seals for industry.
