The band wheels are cast iron for long, productive life. The drive wheel
is mounted on the rotating outer case of the planetary gear reducer.
This direct coupling of the drive wheel to the rotating outer case of
the reducer provides deflection free torque transfer and ensures the
wheel runs true regardless of tension stresses or cutting loads. The
inherent high efficiency of the planetary gear reducer means more power
is delivered to the blade. The idler wheel spindle assemblies
incorporate tapered roller bearings for greater rigidity and long
service life. The wheel tracks the blade so that the back of the blade
contacts the wheel flange to support the back of the band.
