vane air motor / friction-free / fixtured

Fiam air nutrunner motors without clutch feature direct and continuous torque drive. This helps in assuring tightening evenness on all types of joints, including very soft joints. An example will be assembly of steel parts with interposed thick rubber seals. An integrated torque transducer can be added on request to enable measurement of torque value. It collects data, inspects the tightening cycle, and identifies potential errors such as already tightened screws, partially tightened screws, crossed thread, etc.
