The DBH 5815 oil seal is a radial seal with an Lx design that mounts on an 8 mm shaft and seals against a 16 mm housing, with a height of 7 mm. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that can damage bearings, bushings or gears. It is a small but critical part in equipment where the shaft rotates at moderate speed and external contamination shortens service life.

The DBH 5815 is identified by its designation: radial shaft seal with sealing lip and Lx design. The dimensions you need to verify before ordering are the 8 mm shaft diameter, the 16 mm housing diameter and the 7 mm overall height. The Lx design corresponds to a single-lip configuration with spring, suitable for rotating shafts with permanent lubrication. The elastomer and the internal spring work together to maintain contact on the shaft and compensate for small misalignments.

This type of oil seal appears in small electric motors, gear reducers, low-power centrifugal pumps, fans, machine tools and transmission equipment. It is also used in compact gearboxes, conveyor rollers and mechanisms where two environments must be separated: one with oil or grease and another exposed to the environment. In all these cases, the oil seal prevents leaks and protects the bearings or bushings behind it.

To install it, clean the housing and the shaft, check that there are no burrs or marks that could tear the lip, and lubricate the lip with the same grease or oil used in the equipment. Insert the oil seal perpendicular to the shaft, without hitting the lip, using a tube or shim that presses on the outer ring. If the shaft is worn, consider a nearby size or an oil seal with an additional lip. Speed, temperature and the type of fluid determine the lip material.

If you need an equivalent or a different size, send us the part number 5815 along with the shaft, housing and height dimensions, and the type of fluid. A photo of the old part or the assembly drawing also works. With that data we look for the DBH option that fits best or we offer you an alternative within the same radial shaft seal category. You don't need to have the original part number: the correct dimensions are enough.
