For shafts that need a compact radial seal, the DBH 8859 oil seal covers a 6 mm shaft, a 16 mm housing bore and a 7 mm height in the Lx design. Its job is to hold lubricant in place and keep dust, water and particles out of the bearing area. The flexible lip absorbs minor misalignment, so sealing stays consistent in everyday industrial service. MR Industrial Accessories LLC supplies this brand and helps you match the seal to your application.

Reading the code is the quickest way to confirm a match: the 8859 designation fixes the size within the DBH line, and the Lx design describes a sealing lip combined with a reinforced body for cylindrical housings. In practice, the seal measures 6 mm at the shaft, 16 mm at the housing bore and 7.00 mm in height. It works as a radial sealing element on rotating shafts, where it prevents grease or oil from escaping and blocks contamination from reaching the bearings and bushings behind it.

Typical installations include small electric motors, reducers, pumps, fans, machine tools and transmission assemblies. The same size also turns up in automotive, agricultural and general industrial equipment where space around the shaft is limited. Because the shaft diameter is small, these seals are common in compact mechanisms that still need dependable lubricant retention and contamination control. Treat it as a wear part: replace it once leakage appears or the surrounding bearing starts making unusual noise.

Before ordering, compare the three dimensions against your equipment: shaft, housing bore and height. The Lx design suits moderate speeds and low pressures. On assembly, coat the lip with the same oil or grease used in service, press the seal in squarely, and avoid hitting or deforming it. If the shaft surface is worn or rough, plan on replacing the shaft or fitting a wear sleeve so the lip can seat properly.

If you are unsure about the size, send part number 8859 or the dimensions of the seal you are removing. A photo of the housing or the old part also helps. The team can suggest an equivalent size or a close variant from the brands available, and will point out what to check before installation.
