Axial rolling system RR22-2
When precision, efficiency, and reliability come together, real success stories emerge. Thanks to newly designed thread rollers, we are increasing output to around 45,000 parts per roller set—while simultaneously reducing tooling costs and maximizing process reliability. The result: greater performance, greater stability, and a noticeable advantage in production.
