NimCor’s rugged 3-inch air-operated mechanical chucks with self-centering design and positive-grip lugs are easy to mount and easy to use with convenient air valve access. The chucks are ideal for heavy-duty shaftless applications with maximum torque. Positive grip lugs secure the core to the chuck with no slippage. The chuck self-centers as the lugs pneumatically expand. NimCor air mechanical chucks are also available for 6 inch cores and for special core sizes, including 5 in. and 8 in.
