Plymouth Spring Company, Inc. was approached by a customer from the lawn care industry to pin roll 2 to 4 million stainless steel shafts per year. We started by pin rolling the 1.150″ long shafts which had an outside diameter of .002″. Then we tumble polished and heat-treated the 302 stainless steel shafts to a Rockwell hardness of 52. Throughout the entire process, we held tight overall tolerances of ±.005″ and a straightness tolerance of .002″. The shafts were dimensionally inspected and then shipped to the client’s Riviera Beach, Florida location.
