Product Details:

REXROTH 0608750109-102 is a strain-gauge precision torque transducer for Rexroth legacy servo nutrunner tightening spindle, matched with SZ2 interface spindle modules for small and medium torque closed-loop fastening measurement. It converts mechanical torsion load into analog signal output, maintaining excellent linearity and repeatability for quality-critical bolt joints. This legacy transducer is discontinued, and most available units are refurbished spare replacement parts for old automotive assembly lines.

This torque transducer transmits real-time torque analog signal to the matched Rexroth tightening controller. Combined with resolver or incremental angle feedback, it completes dual torque-angle closed-loop supervision, supporting common tightening sequences including torque control plus angle monitoring and yield point detection. Shielded signal wiring layout reduces electromagnetic noise interference inside industrial cabinets equipped with inverters and welding equipment.

This variant is a standalone sensing component without integrated drive or brake. It is installed between the gearbox and SZ2 square drive output of the tightening spindle. The standardized SZ2 flange interface supports direct replacement and quick assembly swap. The internal strain gauge circuit adopts built-in temperature compensation structure to reduce measurement drift under continuous cyclic load. The sealed housing reaches IP54 protection grade to resist workshop dust and incidental coolant splash. Optimized elastic structure minimizes cross-talk interference and guarantees stable torque reading under vibration workshop conditions.

It can be calibrated and parameterized via Rexroth tightening software, supporting fastening curve recording and batch production data traceability for assembly quality management. Every finished transducer passes factory validation including static torque calibration, linearity inspection, cyclic load endurance test and vibration stability test to guarantee reliable measuring performance in multi-shift automated fastening production lines.

It is widely deployed on automotive engine component assembly stations, household appliance fastening lines, new energy small module bolt joining equipment and static torque calibration fixtures. Typical application scenarios include spindle torque feedback modules, mixed-model small torque fastening measuring units, safety-critical bolt connection monitoring platforms and torque calibration fixtures. Automation integrators select this Rexroth transducer variant for its stable analog signal output, compact SZ2 compatible structure and seamless matching with Rexroth nutrunner tightening ecosystem.
