The DBH 8366/85 radial shaft seal is a lip seal that closes off the passage of oil or grease between a rotating shaft and its housing. With 21.00 mm shaft diameter, 39.60 mm housing and 10.00 mm height, and Lz design, it is press-fitted into covers, boxes and housings to retain lubricant and stop the entry of dust, water or particles. It is a wear part: when leakage appears, it is replaced by size.

This item is a seal from the DBH line, identified by the designation 8366/85. Its dimensions are 21.00 mm shaft diameter (d), 39.60 mm housing diameter (D) and 10.00 mm height (h). The Lz design corresponds to a seal with a sealing lip and a construction configuration specific to that variant. The elastomer and internal spring are confirmed against the manufacturer's data sheet at the time of quoting.

It is used in equipment where a shaft passes through a lubricated housing: electric motors, gear reducers, pumps, gearboxes, mixers and machine tools. It also appears in rollers, conveyors and transmission shafts that run with grease. In all those cases it performs two functions at once: retaining the lubricant inside the assembly and preventing contaminants from entering from outside, which extends the life of bearings and gears.

To select it, verify that the shaft diameter, housing and height match the dimensions of the original seal. The shaft must be clean, free of burrs or wear marks in the contact area, and the housing free of deformation. When installing it, lubricate the lip, seat the seal well perpendicular and press evenly to the bottom. If the shaft shows grooving, it is advisable to consider a seal with the lip in another position or a wear sleeve.
