A radial shaft seal from the DBH line, part number 8166, sized for a 17 mm shaft, a 35 mm housing bore and a 7.00 mm height, built to the Lx design. Its job on the machine is straightforward: hold oil or grease in the housing and keep dust, water and particles out, so the bearings and gears behind it stay protected.

Reading the code is the quickest way to confirm a match. The 8166 designation carries the size: shaft 17 mm, housing 35 mm, height 7.00 mm. The Lx suffix refers to how the lip and outer body are constructed, which determines how the seal sits in the bore and how it contacts the rotating shaft. Because the lip runs against the shaft in motion, this is a precision part rather than a simple gasket.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, compressors and transmission shafts, as well as in general power transmission assemblies. Whatever the machine, the function is the same: keep lubricant where it belongs and block contamination from outside. Doing that reliably is what lets bearings, bushings and gears reach their expected service life. The compact 17 x 35 x 7 mm envelope also suits equipment where radial space is tight.

Before ordering, compare the shaft diameter, housing bore and height against the actual seat on the machine. The shaft surface should be smooth and free of scratches or wear, and the bore clean with no burrs left from previous work. At installation, coat the lip with the same oil or grease the unit runs on, drive the seal in with a tool that will not catch or tear the lip, and check that it ends up square to the shaft. A seal pressed in crooked or forced into place is a common cause of early weeping.

If you need a replacement or an equivalent for the DBH 8166, send the full part number along with the shaft, housing and height measurements, plus a photo or the old sample if you have it. With those details we can search our seal and oil seal range for a match, or confirm whether the next size up or down is the closer fit. We can also point you to the lip design that suits your lubricant and operating conditions.
