The DBH 5151Sil radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and stop the ingress of dust, water or particles. With 38 mm shaft diameter, 52 mm housing diameter and 8 mm height, and Lx design, it is a commonly used size in gearboxes, pumps and electric motors. MR Accesorios Industriales supplies this official brand and helps you confirm the correct variant for your equipment.

This item is an oil seal from the DBH line, identified as 5151Sil. Its dimensions are 38.00 mm shaft diameter (d), 52.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design indicates the lip and metal body configuration according to the manufacturer's nomenclature. It is a single-lip seal, designed for rotating shafts with permanent lubrication, and is press-fitted into the housing with the lip facing the lubricant side.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. In all these cases it performs the same function: keeping oil or grease inside the assembly and preventing the entry of contaminants that accelerate wear of bearings and gears. It is also used as a secondary closure in equipment where there is splashing or a dusty environment.

To choose the right seal, verify that the shaft and housing diameters match the values in the product page, that the height is compatible with the housing depth and that the lip runs on a surface free of grooves or burrs. If the shaft is worn, consider a wear sleeve or a nearby size. Speed, temperature and type of lubricant also condition the lip material; therefore, looking only at the dimensions is not enough.

If you need an equivalent or a close size, send us the code 5151Sil along with the shaft, housing and height dimensions, and a photo of the old seal if you have it on hand. With that data we can look for the same size in another brand or an alternative from the DBH line itself. We can also guide you if the Lx design is not the one that corresponds to your equipment and a different type of lip or case is needed.
