The Rexroth Ergo Spin provides all the cutting-edge technology needed to control and monitor tightening processes. The hand-held nut runner comes in a design that covers single-channel operation and multi-channel operation with up to 40 tightening channels and can be seamlessly integrated into stationary tightening systems from Rexroth. Using the BS300 software ensures that the Ergo Spin can be quickly and easily parameterized and programmed. Visualization of results and system errors is done on the display in the LTU350 servo amplifier. The SD301 system display is also available to visualize tightening results right at the workplace and can be installed anywhere in the station.
