The DBH 5815 oil seal is a radial shaft 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 job is to keep lubricant inside the assembly and block dust, water or particles that could damage bearings, bushings or gears. It is a small but critical part in equipment where the shaft turns at moderate speed and external contamination shortens service life.

The DBH 5815 is identified by its designation: radial shaft seal with a 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 a 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, gearboxes, low-power centrifugal pumps, fans, machine tools and transmission equipment. It is also used in compact gear cases, conveyor rollers and mechanisms where two environments must be separated: one with oil or grease and another exposed to the surroundings. 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 striking the lip, using a tube or spacer that presses on the outer ring. If the shaft is worn, consider 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 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 offer you an alternative within the same radial shaft seal category. You don't need the original part number: the correct dimensions are enough.
