The DBH 5111Sil radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 49.20 mm shaft, 65.06 mm housing and 12.70 mm height place it in medium-sized transmission and rotating equipment. MR Accesorios Industriales carries it as part of its seals and oil seals line for industrial maintenance.

The DBH 5111Sil is a seal with an Mx design, with the three dimensions that define its mounting: shaft diameter 49.20 mm, housing diameter 65.06 mm and height 12.70 mm. The flexible lip runs on the rotating shaft and the metal case is fixed by interference in the housing. That combination of dimensions corresponds to a medium-section seal, intended for shafts where axial space is limited but a reliable closure is needed.

It is used in gearboxes, pumps, electric motors, fan shafts and transmission equipment where oil or grease must be separated from the environment. It also appears in machine tools, washing equipment and processes with water or steam, provided the shaft and housing match the indicated dimensions. In all these cases it performs the same function: prevent leaks and extend the life of the bearing or bushing it protects.

To install it, verify that the shaft is within tolerance and free of burrs, and that the housing has the right diameter and finish. Lubricate the lip before inserting it and apply force on the case, never on the lip. If the equipment runs at high peripheral speed or temperature, choose the lip compound according to those conditions. A poorly seated seal loses effectiveness even if the dimensions are correct.

If you cannot find the 5111Sil or need a nearby size, send us the full code, the shaft, housing and height dimensions, and a photo of the old seal if possible. With that data we look for the equivalent in the same brand or in another line we carry. We can also advise you if the Mx design is not the right one for your application and another lip geometry should be considered.

MR Accesorios Industriales carries the DBH brand as part of its seals and oil seals catalog. To confirm that this code is the one for your equipment, send us the code 5111Sil on WhatsApp and we will verify it against the manufacturer's data sheet. That way you avoid buying a seal that does not correspond and you have the backing of a company with more than 80 years in the industrial sector.
