A new generation
of heavy-duty, .404” pitch professional guide bars has been
developed for professional cutters who demand exceptional performance
and life. The GB .404” pitch Pro-Top was developed with the
cooperation of field-test crews working under varied timber conditions.
GB development engineers analyzed this reliable feedback, comparing
and confirming the bar's impressive laboratory results with those
encountered under tough field conditions.
The resulting .404” pitch Pro-Top represents a completely new
design concept. The body profile has been widened and the nose cartridge
fortified with the new VQ, 11-tooth harvester bar sprocket. This rugged
sprocket was designed to withstand the excessive forces of mechanical
harvesting. It is made of tough, titanium alloy steel--the same alloy
used in GB harvester bars. This extra measure of quality guarantees
the highest performance and durability, and assures that the GB .404-in.
pitch Pro-Top is the finest sprocket nose bar available today. Harvester
bar quality in a chainsaw bar body!
FEATURES:
• One-piece solid body bar with wider profile.
• Extra strong 11 tooth Sprocket, has more “MEAT”
at the sprocket gullet.
• High-tech alloy steel construction with increased resilience
and resistance to bending.
• Induction hardened, precision-ground rails.
• Advanced sprocket geometry that minimizes chain outlet contact
loads and maximizes sprocket strength.
• Nose cartridge manufactured to exacting tolerances to maintain
precision clearances for sprocket rotation.
• High tensile alloy rivet system.
• Precision-ground Swiss bearings lubricated with special high-temperature,
high-adherence grease.
• Fully guaranteed.
BENEFITS:
• Outstanding reliability and added durability.
• Superior materials make bar body much more resilient.
• Long rail life with minimal risk of chipping or rail spreading.
• Smooth chain transport from nose sprocket to bar.
• Rugged, dependable.
• Less chance of breaking sprocket or sprocket teeth.
• Less frictional heating of sprocket/bearing/hub assembly.
• Longer bearing life.
• Resistance to nose spreading.
• Sprocket nose cartridge easy to replace.
