The DBH 8649 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain oil or grease and block the entry of dust and water. Its dimensions are 42 mm shaft, 72.5 mm housing and 12 mm height, with Mx-H design. It is used in gearboxes, pumps, electric motors and power transmission equipment.

This item is a DBH 8649 radial shaft seal, identified by its numeric designation and by the dimensions listed on its product page: 42 mm shaft diameter (d), 72.5 mm housing diameter (D) and 12 mm height (h). The Mx-H design defines the geometry of the lip and the outer case. It is a single-lip seal, with a metal case and elastomer, designed for rotating shafts with permanent lubrication.

Typical applications for a seal of this size include gearboxes, reducers, centrifugal pumps, electric motors, rollers and transmission equipment. In all cases it performs two functions: preventing lubricant from leaking out and blocking the entry of contaminants such as dust, water or particles. It is a wear part, so it should be checked when leaks or noises appear in the seal area.

To select and install a seal, you must verify that the shaft diameter, housing diameter and height match those of the machined housing. The shaft must be clean, free of burrs and deep marks, and the housing free of deformation. When installing it, lubricate the lip with the same oil or grease used in the equipment, avoid hitting it and make sure the lip faces the lubricant side. Forcing it during installation damages the lip and shortens its service life.
