Northfield Precision Instrument Corporation (Island Park, NY) has introduced their Automotive Rubber Grip chuck for automotive “rubber coupling” drive shaft joints. The small collet in the center grips a 14mm I.D. to an accuracy of less than 1/10,000” T.I.R. Three extended fingers simulate “bolting” the flange in place the way it is used in vehicles. The drive shafts are balanced from 3,500 rpm to more than 6,000 rpm.
