Northfield Precision Instrument Corp., a leader in the design and manufacture of precision workholding chucks, introduces their Automobile Rubber Grip chuck. This special chuck grips 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. The (3) extended fingers pass thru (3) bolt holes, expand, and "Face Clamp" only. These fingers simulate "Bolting" the flange in place the way it is used in the vehicles. Drive shafts are balanced from 3,500 rpm to over 6,000 rpm.
