Most chopper-blade seals are afterthoughts — a standard rotary seal pushed past its rated surface speed. The CinchSeal Chopper is a clean-sheet design for the 3,600 RPM chopper shaft on a ribbon blender or fluid bed. Tungsten faces, oil-bath running gear, balanced shaft loads. Designed to outlive the bearings on the chopper itself.
