The DBH 6859 is a radial shaft seal that closes the gap between a rotating shaft and a fixed housing. It keeps lubricant in and contaminants out. The seal measures 48 mm at the shaft, 65 mm at the housing and 10 mm in height, and its Lx-R-AH design combines a retaining lip with a reinforced body and a seat-specific geometry. MR supplies this reference for gearboxes, pumps, motors and other transmission equipment.

This seal is built for assemblies where a shaft turns inside a housing and the lubricant must stay contained. You will find it in gearboxes, centrifugal pumps, electric motors, compressors, mixers, and belt or chain drives. It also appears in machine tools, conveyors and hydraulic systems. Anywhere a lubricated bearing meets a shaft passing through a housing, a seal of this type acts as the barrier against leaks and contamination. Because it is a wear part, replacing it on schedule protects the bearings and helps the whole assembly reach its expected service life.

The DBH 6859 fits a 48 mm shaft, a 65 mm housing bore and a 10 mm height. Its Lx-R-AH designation points to a lip seal with a retaining lip, a reinforced body and a geometry matched to the seat. Elastomers and reinforcements in its construction let it run in continuous contact with the shaft and resist the oils and greases typically found in industrial equipment.

During installation, confirm the shaft is at 48 mm and the housing at 65 mm, with no burrs or marks on either surface. Lubricate the lip with the same oil or grease used in the equipment. Press the seal in perpendicular to the shaft, without striking the lip, using a tube or spacer that bears on the outer ring. The 10 mm height must match the housing depth so the seal stays seated. If the shaft shows wear, consider a version with an auxiliary lip.

To order the DBH 6859 or find an equivalent, send the code stamped on the old seal, the shaft, housing and height dimensions, and a photo if you have one. We can also source an alternative in another brand or with a similar design. MR supplies seals and oil seals for many applications, so ask about this reference or any other you need to replace.
