Cannon 18" DuraLite Chainsaw Bar (68 Drive Links) CSB-C1-18-50-DL-3

The new Cannon DuraLite SuperBar is actually made from a virtually completed SuperBar. After the bar has been grooved and the rails have been flame hardened, we eliminate weight by milling out pockets on either side of the SuperBar, leaving a steel core in the center for strength. The center section is then perforated with holes. This method of construction is based on the same principal that you would see in an I-beam. We then use a special adhesive which not only bonds the steel to two flexible aluminium inserts, one on each side of the bar, but also creates a chemical bond or weld between the two inserts. The new DuraLite SuperBar remails ridged and stiff, has the same quality characteristics as the traditional SuperBar, but weighs about 20% less.
