The DBH 9551 radial shaft seal is a lip seal that is fitted into the housing and runs against the rotating shaft to retain lubricant and block dust, water or particles from entering. Its dimensions of 38.10 mm shaft, 50.36 mm housing and 6.35 mm height place it in medium-sized transmission equipment and pumps. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal for your application.

This item is a DBH 9551 radial shaft seal, identified by part number 9551. Its dimensions are 38.10 mm shaft diameter (d), 50.36 mm housing diameter (D) and 6.35 mm height (h). The Mx design corresponds to a single-lip configuration with spring, suitable for rotating shafts with lubrication. The lip elastomer and the metal body work together to maintain dynamic contact and compensate for small misalignments.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors, fan shafts and power transmission equipment. They also appear in agricultural machinery, process lines and pumping equipment where oil must be separated from the environment. As it is a wear component, it is worth checking when leaks appear or when the shaft shows rubbing marks in the contact area.

To select the replacement, verify that the shaft diameter, housing diameter and height match those of the original seal. Check the condition of the shaft: a scratched or worn surface will accelerate failure of the new lip. During installation, lubricate the lip, insert the seal perpendicular to the housing and avoid hitting it unevenly. If the equipment runs with high vibration or temperature, ask us about compound variants.

If you cannot find part number 9551 or need a nearby size, send us the dimensions of the old seal or a photo of the part. With that data we can cross-reference it with other brands and equivalent series. We can also evaluate Mx design alternatives or other lip configurations depending on the type of lubricant and the shaft speed. The idea is that you are not left with the equipment down for a seal.

At MR Accesorios Industriales we carry the DBH brand as part of our line of seals and oil seals. If you need a quote for the DBH 9551 oil seal or want to ask about a similar size, write to us on WhatsApp with the part number and we will reply with the available alternative.
