The DBH 5815 is a radial shaft seal built for an 8 mm shaft, fitting into a 16 mm bore with a 7 mm height. Its Lx design uses a single sealing lip and a spring to hold lubricant in and keep dust, water, and debris away from bearings and gears. For maintenance teams, it is a small component that prevents bigger failures in rotating equipment.

To select this seal correctly, verify the three key dimensions: shaft diameter 8 mm, housing bore 16 mm, and overall width 7 mm. The Lx configuration means a single lip with a garter spring, suited for shafts that run with permanent lubrication and moderate speeds. The spring maintains lip contact even if the shaft has slight runout or misalignment.

This part fits into compact assemblies where space is limited but sealing is critical. You will find it in small motors, pumps, gearboxes, fans, conveyor rollers, and similar machinery. In each case, the seal separates an oil or grease chamber from the outside environment, protecting internal components from contamination.

During installation, first clean the shaft and housing bore and remove any burrs or scratches that could damage the lip. Apply a thin film of the system lubricant to the lip before pressing the seal in place. Use a flat tool or tube that contacts only the outer metal case, never the lip, and drive the seal squarely into the bore. If the shaft surface is worn, consider a seal with a dust lip or a repair sleeve.

When requesting a quote, provide part number 5815 along with the shaft, bore, and width dimensions, plus the type of fluid being sealed. A photo of the old seal or the assembly drawing helps us confirm the right fit. If you are unsure about the size, send the measurements and we will check them before you order.
