The DBH 5317Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry 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 power transmission equipment. MR Accesorios Industriales sells it as part of its seals and oil seals line.

This item is a DBH brand oil seal, 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 spring, intended 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 oil seal include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases it serves to retain oil or grease inside the assembly and prevent the entry of external agents that accelerate 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 an oil seal such as the 5317Sil, verify that the shaft and housing dimensions match those of the equipment. The Lx design defines the lip type 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 an oil seal with the lip in another position.

With that data we can look for an alternative within the DBH line or other brands we carry. We can also advise you if the Lx design is not suitable for your application and another lip type or material should be considered.
