Product Details:

REXROTH 0608750101 is a strain-gauge precision torque transducer for Bosch Rexroth legacy modular servo nutrunner spindle, acting as core measuring component for closed-loop bolt fastening control. It converts mechanical torque load into stable analog output signal, delivering outstanding linearity and repeatability for safety-critical bolt joints on automotive assembly lines. This legacy transducer is discontinued, and most available units are refurbished spare replacement parts for old fastening stations.

This torque transducer sends real-time torque signal to the matched Rexroth tightening controller. Together with angle feedback from encoder or resolver, it realizes dual closed-loop supervision of torque and angle. It supports mainstream tightening strategies including torque control with angle monitoring and yield point detection. Shielded signal wiring layout effectively suppresses electromagnetic interference generated by inverters and workshop equipment, 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 square drive output of the tightening spindle. Standard flange interface supports direct replacement on compatible Rexroth spindle assemblies. The internal strain gauge circuit 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 interference and keeps stable torque reading under vibration.

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 transducer for its stable analog signal output, high measurement repeatability and seamless matching with Rexroth nutrunner tightening ecosystem.
