CHUCKSNimCor offers a choice of two standard chucks styles – torque chucks and air mechanical chucks – to address almost any shaftless application. Rugged torque chucks, made for continuous duty applications, automatically engage in either direction and offer excellent gripping strength without core damage during insertion or removal. Air-operated mechanical chucks provide a strong, air-assisted, bladderless gripping action that secures cores without slippage under maximum torque conditions. Both chucks feature convenient air valve access through the flange or the outside edge of the chuck. Standard chucks fit cores sizes from 3 to 8 inches. Custom chucks are also available.
