The DBH 5268Sil radial shaft seal is a lip seal that mounts on a 22 mm shaft and seals against a 40 mm housing, with a 7 mm height. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering and wearing down bearings and bushings. It is a wear part: when the lip hardens or a leak appears, it is replaced. MR Accesorios Industriales sells it as part of its DBH seal line.

This item is a seal from the DBH line, identified as 5268Sil. Its dimensions are 22 mm shaft, 40 mm housing and 7.00 mm height, with Lx design. The Lx design defines the geometry of the lip and the metal body, and it is the data point that must be respected when looking for an equivalent part. The 5268Sil designation is not a generic serial number: it is the code DBH uses to identify this particular size and design.

Radial shaft seals of this size are used in small gearboxes, electric motors, centrifugal pumps, fan shafts and power transmission equipment. They also appear in machine tools, conveyors and process equipment where a shaft rotates inside a housing and oil or grease must be separated from the environment. In all these cases the seal works alongside the bearing or bushing, and its failure shows up as lubricant loss or contaminant ingress.

To install it, check that the shaft is within tolerance and free of burrs, and that the housing has no dents or remnants of the old seal. Lubricate the lip before inserting the part and use a tool that presses on the outer diameter, never on the lip. If the shaft is worn, has a marked wear track or a groove, the new seal will not seal even if the size is correct. In that case it is worth evaluating a repaired shaft or a seal size with an offset lip.

If you need an equivalent or a nearby size, send us the code 5268Sil along with the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can compare against other lines and see whether there is an alternative in the same size or a close size. We can also review whether the Lx design is right for your application or whether another lip type is better suited to the speed and lubricant type.

MR Accesorios Industriales sells the DBH brand as part of its seal and oil seal line, along with bearings, housings, power transmission and lubricants. If you have the code on hand, write to us on WhatsApp and we will quote it. If you do not have it, send us the shaft, housing and height dimensions and we will look it up by size.
