HA5C4-T

The HA5C4-T is a single-axis rotary unit with four 5C collet noses. The “-T” indicates the unit has thrust bearings to handle higher axial loads. Always select the -T version when planning to use a tailstock to support long workpieces. Tailstock thrust must not exceed 800 lb (3559 N).

Clamp your parts using standard 5C collets, or chuck them by threading a 3-jaw chuck to the spindle nose. This unit comes with a manual collet closer. Optional pneumatic collet closers are also available.

Note: Requires a Haas mill with 4th-axis drive and NGC software version 100.19.000.1100 or later for full 4th-axis operation. Stand-alone operation requires a Haas rotary control box shipped after November 10, 2021, with software version 26.32 or newer.
