Ingersoll grand Carbon Fiber Torque Folding Arm | Spring-Balanced Reaction Support Arm for Electric Tightening Tools
This carbon fiber folding arm features a newly designed arm structure. The carbon fiber material greatly reduces overall weight, delivering a lighter and more comfortable operating feel, effectively reducing operator fatigue and improving work efficiency. It comes standard with a spring balancer for easy ordering and can be directly paired with electric tightening tools to counterbalance tool weight and tightening reaction force.
All guide structures adopt high-quality linear bearings to ensure operation accuracy and long-term reliability. It is available in two categories — Basic Type and Positioning Type — covering a reaction torque range of 10–150 Nm. The Positioning Type supports DC24V power supply and 0–10V absolute analog output for tightening position monitoring. It is widely compatible with industrial tightening workstations in automotive final assembly, electromechanical assembly and 3C electronics industries

Carbon Fiber Lightweight Design for Comfortable & Efficient Operation
The main arm body is made of carbon fiber, with significantly reduced weight compared with traditional metal folding arms. Operators can move and align the tool more easily. It greatly reduces arm strain during long continuous shifts, effectively lowering fatigue and improving efficiency and comfort at assembly workstations.
Standard Spring Balancer for Ready-to-Use Deployment
The product comes with a matched spring balancer as standard, which accurately counterbalances the weight of the tool and arm body, enabling floating positioning of the tool within the working range. No additional balancing device is required, with a simple ordering and installation process for quick production line implementation.
High-Precision Linear Bearings for Stability & Durability
All guide positions adopt high-quality linear bearings, featuring smooth movement and low backlash, ensuring tool alignment accuracy and reliable repeat positioning. With low wear under long-term high-frequency use and a long service life, it adapts to the high-intensity, high-cycle operation demands of industrial production lines.
Dual Versions with Full Range Coverage for Flexible Selection
Two versions are available — Basic Type and Positioning Type — covering a reaction torque range from 10 Nm to 150 Nm, compatible with tightening tools of different specifications. The Positioning Type supports DC24V power supply and 0–10V absolute analog output, and can be connected to production line control systems for tightening position traceability and error-proofing control.
Standardized Interface Design for Strong Compatibility
Equipped with a universal collet as standard, it supports vertical installation of pistol-grip tools and is compatible with mainstream brands of electric tightening wrenches. With standardized installation dimensions, it can directly replace traditional metal folding arms without major workstation modification, achieving low-cost production line upgrade.
