Since this shuttle type is primarily used for longer fin lengths and heavy fin stock materials, the arms are supported on recirculating ball-type bushings, which run on turn ground and polished shafting. In addition, the arms maybe separated so the neither arm is located under the Vacuum Unit, which is helpful during set up of the die. The main Advantages of this type of shuttle is that it can be used for longer fin lengths, if purchased with length increasing options.
