This is an Universal Ball-Lok (UBL) Power Chuck in Good condition.
Max. Draw Bar Pull Force lbs: 12,000
Unit has a 9.625"/244mm spindle mount.
Universal ball-lok pull down compensating type chuck. For both external & internal chucking.
The compensating features of this chuck allows the chuck jaws to compensate for any eccentricity between the chucking diameter and the datum diameter. The centralizing device is usually an arbor, plug or center mounted on the face of the chuck. It then acts as the centralizing device which establishes the axis of rotation for the datum diameter in the work piece. The diameters being turned will then be concentric to the datum diameter.
