KR008 Side-Mounted Carbon Fiber Torque Reaction Arm
Designed for workstations with limited installation clearance, the KURAN KR008 combines a compact folding carbon fiber structure with pneumatic tool balancing and adjustable damping. It supports reaction torque up to 100 Nm, with flexible mounting options and optional XY / XYZ position detection to match your workstation layout and process-control needs.
Working radius and vertical stroke vary by arm-length configuration.
Is KR008 Right for Your Workstation?
Consider the KURAN KR008 when installation space is limited and your tightening tool needs compact, folding support. Start with the available mounting position, then check whether the arm can reach every fastening point without interfering with surrounding equipment.
Limited Overhead Clearance
Frames, enclosures or nearby equipment may restrict the space above your workstation. KR008 offers a compact folding structure that can be evaluated for layouts where a taller support arrangement would be difficult to install.
Check available height and the full vertical movement path.
Side-Mounted Installation
If your workstation layout favors a side mounting position, KR008 can provide tool support from that location. Select the mounting side and folding direction around operator access, fixture placement and the required tightening positions.
Confirm mounting strength, location and folding direction.
Multiple Fastening Points in a Compact Area
When several fastening points sit within a restricted work area, the folding arm helps you reposition the tool between them. Match the arm lengths and vertical stroke to your fastening layout, including the nearest and farthest points.
Verify point coverage and clearance around fixtures.

- Confirm that your selected arm configuration can reach every required tightening point.
Mounting Options and Folding Direction
Match your KURAN KR008 installation to the available mounting structure, working height and fastening layout. Select the folding direction together with the mounting position to maintain clearance throughout the tool’s movement.
Side-Mounted Installation
Mount the arm from a suitable side support when the workstation layout favors lateral installation. The folding structure and vertical movement should be checked against the fixture, tool approach and nearby equipment.
Confirm before selection: mounting surface strength, installation height and clearance across the full movement range.
Top-Mounted Installation
A top-mounted configuration can be evaluated when a suitable overhead support is available. Match the mounting height and extension components to the tool’s required working position and vertical travel.
Confirm before selection: overhead support strength, mounting height, extension length and fastening point coverage.
Column / Bench Mounting
KR008 also supports column-based configurations. If you prefer a bench-mounted support, share your workstation dimensions so KURAN can review the column height, mounting components and structural requirements.
Left Fold or Right Fold?
KR008 is available in left-fold and right-fold configurations. Use the KURAN reference diagram to identify the required direction, then check the arm’s movement against your workstation layout.
Include the operator position, mounting location and fastening points in your layout drawing. This helps confirm the folding direction and check for interference with fixtures or surrounding equipment.

Lightweight Movement and Adjustable Tool Support
The KURAN KR008 combines a carbon fiber arm structure, pneumatic tool balancing and adjustable damping to support repetitive tightening tasks. Each feature addresses a different part of tool handling: moving the arm, supporting the load and managing rotational movement.
Carbon Fiber Structure
The carbon fiber arm combines low structural weight with resistance to reaction torque. For tasks that require frequent repositioning, the lightweight structure helps reduce the effort involved in moving the arm between fastening points.
Easier repositioning during repetitive assembly.
Pneumatic Tool Balancing
A balancing cylinder and precision pressure regulator allow the support force to be adjusted for the tool load. When correctly configured, the system helps reduce the effort needed to raise, lower and guide the tightening tool.
Adjustable weight support for smoother vertical handling.
Adjustable Damping
Adjustable damping lets you tune rotational resistance to suit the operating task. It helps balance smooth movement with stable positioning, reducing unwanted swinging while the operator guides or parks the tool.
Controlled rotation with more stable tool positioning.
Choose Your KR008 Configuration
Start with the mechanical layout, then select the position detection and signal options your process requires. KURAN can help match the configuration to your tool, fastening points and available installation space.
Define Your Mechanical Configuration
Arm Lengths and Vertical Travel
Select the horizontal and folding arm lengths around the nearest and farthest fastening points. Check the required vertical travel and clearance throughout the movement path.
Mounting Method
Choose a mounting arrangement that suits your workstation structure and working height. Confirm the mounting components and support rigidity for the selected layout.
Left Fold or Right Fold
Use the reference diagram above to identify the required folding direction. Consider the operator position, fixture arrangement and potential interference with nearby equipment.
Select Your Position Detection Option
No Position Detection
A sensor-free configuration provides mechanical reaction torque support and tool balancing without position feedback from the arm.
XY Position Detection
An XY configuration provides horizontal position feedback. With a compatible control system, this information can support verification of the intended fastening position.
XYZ Position Detection
An XYZ configuration adds vertical position feedback to XY detection. A compatible control system can use this information when fastening location verification also depends on tool height.
Sensor Signal Options
0–10 V Analog Output
RS485 Digital Communication
Signal options apply to sensor-equipped configurations. Select the interface to match the receiving controller. Position verification, sequence control and tool enable logic require a compatible controller, tool interface and configured workstation program.
KR008 Technical Specifications
Compare the standard KR008 arm-length combinations with their corresponding maximum working radius and vertical stroke. Use these dimensions alongside your tool load, mounting position and fastening layout to identify a suitable configuration.
