Guide Shaft Polar 80 El

Pull Arm Guide Shaft

Machines: Polar 80 EL paper cutters.

Size: This 11mm diameter by 11" long.

This alignment rod fits up through the center of the pull arm to prevent it from flapping around and causing damage when the shear bolts break. It is made from centerless ground drill rod for maximum toughness. 

This guide shaft is held in place with a dowel pin.  The guide shaft must be drilled in place to install it.  Many cutter rebuilders will tap out the dowel pin hole in the lower arm and install a set screw. This will prevent having to drill out the guide shaft each time it is replaced.
