Iggesund Blue Line JW Harvester Guide Bars for JPS sawing systems. The strongest ever harvester bar with a unique metal alloy, that in combination with an improved tempering technique makes them stronger, more robust and more rigid so they are able to withstand all kinds of conditions. Blue Line’s material properties also reduce bar vibrations, which improves efficiency, provides straighter cuts, reduces wear and tear and ensures a longer life span. Iggesund Forest’s Blue Line series is also equipped with a nose sprocket with specially hardened shims for optimal performance. This smart solution minimizes the risk for costly and time consuming nose sprocket breakdowns and eliminates the need for replaceable tips. Available in lengths from 64 cm to 80 cm.
