The DBH 5317Sil radial shaft seal is a lip seal mounted in the housing and closing on the rotating shaft to retain lubricant and block the ingress of dust, water or particles. With dimensions of 30 mm shaft, 42 mm housing and 8 mm height, and Lx design, it is a common replacement part in gearboxes, pumps, electric motors and transmission equipment. MR Accesorios Industriales supplies it as part of its line of seals and oil seals.

This item is a seal from the DBH brand, identified by the code 5317Sil. Its dimensions are 30.00 mm shaft diameter (d), 42.00 mm housing diameter (D) and 8.00 mm height (h). The Lx design corresponds to a single-lip seal with a spring, designed for rotating shafts with lubrication. The elastomeric lip runs on the shaft and the outer metal case fits into the housing to maintain sealing. It is a wear part that is replaced when lubricant leakage or contaminant ingress appears.

Typical applications of this seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases it fulfills the function of retaining the oil or grease inside the assembly and preventing the entry of external agents that accelerate the wear of bearings and gears. It is also used in machine tools, process equipment and assemblies where the shaft rotates inside a fixed housing.

To select and install a seal such as the 5317Sil, verify that the shaft and housing dimensions match those of the equipment. The Lx design defines the type of lip and its orientation. During installation, lubricate the lip with the same service oil or grease, insert it perpendicular to the shaft and avoid hitting or deforming it. A damaged lip or a shaft with scratches or wear causes premature leaks. If the shaft shows wear, consider a repair sleeve or a seal with the lip in another position.

If you need a seal equivalent to the 5317Sil, send us the full code, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can look for an alternative within the DBH line or other brands we supply. We can also advise you if the Lx design is not suitable for your application and it is worth evaluating another type of lip or material.
