FlexArm Torque Reaction Arms: Ergonomic Solutions for Safer, More Consistent Fastening
Repetitive-torque fastening applications can take a serious toll on operators and production quality. Without proper support, torque tools transfer reaction forces directly to the operator, leading to fatigue, strain, and inconsistent results. FlexArm torque reaction arms are designed to solve this problem by absorbing torque reaction and supporting tool weight. Improving ergonomics, safety, and consistency on the shop floor.
Two of the most popular models, the AR-40 and LR-40 torque reaction arms, are engineered to handle demanding industrial applications while integrating seamlessly with common fastening tools.
What Is a Torque Reaction Arm?
A torque reaction arm is an ergonomic support system that absorbs the reaction force created when torque tools tighten fasteners. Instead of the operator resisting that force, the arm manages it mechanically, allowing the operator to guide the tool with less effort and more control.
The result is reduced strain on wrists, arms, and shoulders, and more repeatable torque results across every cycle.
AR-40 Torque Reaction Arm: Compact Control for Fixed Workstations
The FlexArm AR-40 torque reaction arm is designed for applications where space is limited and reach requirements are more controlled.
AR-40 Benefits:
- Compact design ideal for tight or fixed workstations
- Absorbs reaction torque from repetitive-torque tools
- Supports tool weight to reduce operator fatigue
- Improves fastening consistency and alignment
The AR-40 is commonly used in bench-mounted or fixture-based assembly operations where repeatability and operator comfort are critical.
LR-40 Torque Reaction Arm: Extended Reach and Flexibility
For applications requiring more movement or a larger work envelope, the FlexArm LR-40 torque reaction arm provides extended reach without sacrificing ergonomic performance.
LR-40 Benefits:
- Longer reach for larger assemblies or multi-location fastening
- Smooth, controlled movement throughout the work area
- Reduces operator strain during repetitive torquing processes
- Ideal for dynamic and flexible workstation layouts
The LR-40 is a strong fit for assembly lines, larger parts, and operations where operators need freedom of movement while maintaining control.
Compatible Tool Mount Options
FlexArm torque reaction arms are designed to work with a wide range of pneumatic and electric torque tools, making them easy to integrate into existing production environments.
Common Tool Mount Options:
- Standard tool mounts for popular torque tools
- Custom mounting solutions for unique tool geometries
- Adaptable interfaces for shops using multiple tools
These options ensure your torque reaction arm works with your current tools.
Why Shops Invest in Torque Reaction Arms
Adding a torque reaction arm like the AR-40 or LR-40 delivers benefits that extend beyond ergonomics:
- Improved operator safety by reducing exposure to torque reaction
- Higher productivity through reduced fatigue and smoother workflows
- Better fastening quality with consistent torque application
- Scalable solutions that adapt as tooling or applications change
For shops focused on efficiency, quality, and workforce safety, torque reaction arms are a smart long-term investment.
Conclusion
Whether you need a compact solution or extended reach, the FlexArm AR-40 and LR-40 torque reaction arms provide ergonomic support, torque control, and compatibility with common industrial tools. By removing torque reaction from the operator’s hands, these arms help create safer, more productive workstations designed for real-world manufacturing demands.
