Product Details:

REXROTH 0608750084 is a strain-gauge based precision torque transducer for Bosch Rexroth modular servo nutrunner tightening spindle, serving as the core measuring component for closed-loop fastening quality control. It converts mechanical torque load into analog output signal, delivering excellent linearity and repeatability for safety-critical bolt joints on automotive assembly processes. This legacy transducer part is discontinued, and most available units are refurbished spare replacements for old fastening stations.

This torque transducer transmits real-time torque signal to the matched Rexroth tightening controller. Combined with angle feedback signal from encoder or resolver, it realizes dual closed-loop torque and angle supervision. It supports mainstream tightening modes including torque control with angle monitoring and yield point detection. The shielded signal cable layout effectively suppresses electromagnetic interference generated by inverters and welding equipment on the workshop floor, maintaining stable measurement data transmission.

This variant is a standalone sensing component without integrated drive or brake. It is installed between the planetary gearbox and the square drive output of the tightening spindle. The standardized flange interface supports direct swap on compatible Rexroth spindle assemblies. The internal sensing element adopts temperature compensation design to reduce measurement drift under continuous cyclic load. The transducer housing reaches IP54 protection grade to resist workshop dust and incidental coolant splash. Optimized mechanical structure minimizes cross-talk and signal distortion, keeping stable torque reading under vibration conditions.

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

It is widely deployed on automotive powertrain assembly stations, new energy battery module fastening lines, heavy mechanical component bolt joining equipment and static torque calibration fixtures. Typical application scenarios include spindle torque feedback modules, safety-critical bolt measuring units, mixed-model assembly sensing components and torque verification platforms. Automation integrators select this Rexroth torque transducer for its stable analog output, high measurement repeatability and seamless matching with Rexroth nutrunner tightening ecosystem.
