Hardinge Emergency Step Chucks used on A2-5 and A2-4 5C spindles have the same criteria as regular step chucks except the shank is longer.  The closers are made of steel.

  • The A2-4 Closer is used on the Hardinge CONQUEST GT Lathe
  • The A2-5 Closer is used on the Hardinge CHNC-5C and HXL A2-5 5C spindle - the same closer used on all A2-5, 16C Spindles

Because these 5C Step Chucks have a longer shank than standard 5C Step Chucks, they can only be used on Hardinge CONQUEST GT, CHNC-5C, and HXL A2-5 5C Lathes.  A2-5 hardened and ground step chucks are available as special orders.


  • A2-4 Closer (GT Machine): This closer is a special make.
