Workstation Fit
Is KR007 Right for Your Workstation?
Start with your tightening task, fastening-point layout and tool-handling needs to assess whether KR007 is a suitable option for your workstation.
High-Torque Tightening
Your fastening process requires mechanical support for tightening reaction torque. Select the arm capacity according to your maximum required tightening torque.
Tool Movement Between Fastening Points
You need to move the supported tool between multiple fastening points. Check that a linear-arm arrangement suits their positions and the required tool orientation.
Support for Tool Weight
Your tool needs weight support during repeated tightening cycles. Confirm the complete supported tool load when choosing a balancer configuration.
Design Features
KR007 Design Features and Practical Benefits
A robust linear structure, flexible mechanical movement and spring-balancer support form the core of the KR007 design. The horizontal arm length can also be customized.

Workstation Integration
Tool Connection and Workstation Installation
Prepare your KR007 installation by checking the tool interface, complete supported load and mounting space. These details help KURAN assess how the arm will fit into your workstation.
-
Confirm the Tool Connection
Provide the tool model, interface dimensions and required tightening orientation. Include any adapter or socket details so KURAN can assess the connection between the tool and the arm.
-
Match the Balancer to the Total Load
Calculate the combined weight of the tool, adapter, socket and other supported attachments. Use this total when selecting the spring balancer, and confirm its adjustment for the installed assembly.
-
Check Mounting and Movement Clearance
Use the selected model’s base dimensions to plan the mounting position. Confirm that the supporting structure and fixings can withstand the reaction loads, with enough clearance for the arm and tool throughout the intended movement.
Share your tool details and a workstation drawing with KURAN to discuss the tool connection, balancer and mounting arrangement.
Discuss Your WorkstationKR007 Frequently Asked Questions
Find answers about KR007 torque capacity, tool load, position detection and customization before confirming your configuration.
The KR007 series offers standard torque ratings of 150, 300, 500 and 1000 Nm. The maximum rating is 1000 Nm on the KR007-LN-1000R660. Select a model according to your maximum required tightening torque and confirm the configuration with KURAN.
No. Three-axis movement describes the arm’s mechanical movement. Standard KR007-LN models do not include position detection; the N means no sensor. If your process requires fastening-point detection, share that requirement with KURAN so a suitable model can be assessed.
Use the total supported weight, including the tightening tool, adapter, socket and other attachments. Share this total with KURAN to confirm a suitable spring balancer and arm configuration.
Yes. The KR007’s horizontal arm shaft length can be customized. Provide your fastening-point layout, proposed mounting position and available installation space so KURAN can assess suitable dimensions.
Share your maximum tightening torque, tool model, total supported weight, fastening-point layout and available installation space. A workstation drawing or photo is also helpful. If some details are unknown, send the information you have so KURAN can identify what else is needed.
