CCI's Quarry Duty "AR" (abrasive resistant) Wing Pulleys are constructed with AR400 3/4" x 2" heavy contact bars and are recognized in the industry as a true problem solving pulley. All CCI Quarry Duty "AR" Wing Pulleys utilize the unique 'end-pipe' design, which offers ultimate protection against wing folding and hub-weld fatigue. Our 3/4" AR400 contact bar yields maximum life in super abrasive applications where our competitors thinner A36 mild steel bar does not. Additionally, our 1/2" thick wing and 5/16" gussets offer higher structural support in aggressive applications.

All CCI Quarry Duty "AR" Wing Pulleys utilize full depth keyed bushings which offer maximum clamping force on the shaft and minimize "pulley walking." The Quarry Duty "AR" wing pulley has changed the industry and solved the problem of premature bar wear plaguing users in some of the most aggressive applications.
