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 a 21.00 mm shaft diameter, 39.60 mm housing diameter 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 with 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 housing containing lubricant: electric motors, reducers, pumps, gearboxes, mixers and machine tools. It also appears in rollers, conveyors and transmission shafts that run with grease. In all these cases it performs two functions at once: retaining 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 diameter 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, lubricate the lip, seat the seal squarely and press evenly all the way in. If the shaft shows grooving, it is advisable to consider a seal with the lip in a different position or a wear sleeve.

To quote code 8366/85, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part.
