The DBH 6684Pol is a radial lip seal sized for a 92 mm shaft in a 106.50 mm housing bore, with a 5.40 mm height. Its Lx-R configuration pairs a primary sealing lip with a secondary lip that faces the dirty side of the assembly, so it holds lubricant in and keeps dust, water and particles out. You will find this style of seal on gearboxes, pumps, motors and transmissions where a shaft turns inside a machined bore.

Reading the code is the quickest way to confirm a replacement. The 6684Pol number fixes the size and the lip arrangement, and the Lx-R suffix tells you the seal has both a main lip and an outer protective lip. In practice that means the seal is built for spots where grit, washdown spray or airborne dust reach the exposed face of the housing.

The numbers to check against your equipment are shaft 92 mm, housing 106.50 mm, height 5.40 mm. All three have to line up before the seal goes in. A shaft that is scored, burred or pitted will chew through a new lip, and a bore without a clean entry chamfer can shave the lip on the way in. Wipe the shaft, inspect the chamfer, put a light film of lubricant on the lip, and press the seal in squarely rather than striking it.

Treat the seal as a wear item. It belongs on the inspection list at every service interval, since a weeping lip usually shows up before a bearing fails. Catching it early keeps lubricant where it belongs and stops contaminants from reaching the bearings and gears behind it.

If you are cross-referencing, send the part number 6684Pol or the dimensions 92 x 106.50 x 5.40 mm and the team can look for options in the DBH line or from other brands on the shelf. Manufacturer data is confirmed before anything is quoted. If the Lx-R layout does not suit your application, say so and you will get guidance on what does.
