QUESTIONS YOU MIGHT CARE ABOUT
FAQ
How do I select the right torque reaction arm based on tightening torque?
The primary selection criterion for a torque reaction arm is the maximum output torque of the fastening tool, not the nominal or commonly used torque setting. KuRan recommends that the rated torque capacity of the reaction arm exceed the tool’s maximum torque by 20–30% as a safety margin to ensure reliable operation under peak loads or abnormal conditions. Additional factors such as tool weight, tightening direction, working reach, and workstation space constraints should also be considered. KuRan provides application-based selection support to help customers avoid under- or over-specification.
Are KuRan torque reaction arms compatible with different brands and types of fastening tools?
Yes. KuRan torque reaction arms are designed with a high level of compatibility and can be used with most mainstream electric, pneumatic, cordless, and pulse fastening tools. Through interchangeable or custom tool sleeves, the arms can accommodate different tool housings, mounting interfaces, and flange designs. During the selection process, customers only need to provide the tool model, weight, and interface details, and KuRan will confirm compatibility or develop a tailored solution if required.
What is the difference between positioning and non-positioning torque reaction arms, and how should I choose?
Positioning torque reaction arms allow the tool to be held in a fixed and repeatable fastening position, making them ideal for applications with fixed cycles, defined fastening points, and high consistency requirements. Non-positioning arms provide greater freedom of movement and are better suited for multi-angle operations, variable workstations, or applications with frequent product changeovers. The optimal choice depends on the production process, workstation layout, and required level of operator flexibility. KuRan can assist in evaluating the most suitable option for your application.
Will a torque reaction arm affect tightening accuracy or operator flexibility?
No. When properly selected and installed, a torque reaction arm does not negatively impact tightening accuracy. On the contrary, by stabilizing the tool and eliminating the need for operators to resist reaction torque manually, it can improve fastening consistency and repeatability. KuRan arms are engineered with low-friction bearings and optimized kinematics to ensure smooth, natural movement without interfering with axial tool output or operator control.
How do torque reaction arms reduce operator fatigue and injury risk?
During fastening, all reaction torque is absorbed and transferred through the arm structure to the floor or supporting system, rather than through the operator’s body. In addition, integrated spring balancers offset the weight of both the tool and the arm, allowing the operator to guide the tool with minimal effort. This significantly reduces stress on the wrists, shoulders, and lower back, helping to prevent fatigue accumulation and repetitive strain injuries (RSI), while supporting ergonomic and occupational safety requirements.
Can KuRan provide customized solutions for specific workstations and applications?
Yes. In addition to standard models, KuRan offers comprehensive custom and application-specific torque reaction arm solutions. Customization options include torque capacity, working range, mounting method, tool interface, material selection (such as carbon fiber), and multi-axis or multi-tool configurations. At the early project stage, KuRan can review workstation layouts, process requirements, and tool data to deliver a technically optimized solution that ensures long-term safety, efficiency, and reliability in production environments.
