KR001 Direct-Push Torque Reaction Arm
Space-Efficient Direct-Push Structure with 360° Arm Rotation
The KR001 combines adjustable push-pull reach with 360° rotation around a fixed column, providing a more space-efficient movement envelope than the KR001 Dual-Axis model. Its spring balancer supports the tightening tool and moving arm components, while the rigid arm structure transfers reaction torque to the workstation base. Choose from 25, 50, or 100 Nm configurations with no position detection, XY detection, or XYZ position detection.

Is the KR001 Direct-Push Right for Your Workstation?
The KR001 Direct-Push Torque Reaction Arm is intended for fixed tightening stations that need adjustable push-pull reach and 360° rotation within a relatively compact movement envelope. Before selecting a configuration, confirm the maximum tightening torque, required working radius, tool load, installation clearance, and whether the process needs position detection.
Choose the KR001 Direct-Push When
- The maximum tightening torque is between 25 and 100 Nm.
- The tool needs adjustable push-pull reach and rotation around a fixed mounting point.
- The workstation benefits from a more compact movement envelope than a folding dual-axis arm.
- The available space provides sufficient clearance for the required 680–900 mm working radius.
- The process requires mechanical support alone or optional XY / XYZ position detection.
Consider Another Torque Arm Structure When
- The arm must fold around fixtures or obstacles so the tool can approach fasteners from different directions.
- The maximum tightening torque exceeds 100 Nm.
- The workstation has limited installation height or insufficient radial clearance.
- The application requires extended reach, floor-mounted support, or wide-area gantry coverage.
- The complete tool load or mounting arrangement falls outside the standard KR001 configuration range.
How the KR001 Direct-Push Torque Reaction Arm Works
The KR001 combines adjustable push-pull travel with 360° rotation around a fixed vertical column. The spring balancer compensates for the weight of the tightening tool and moving arm components, while the rigid arm structure transfers reaction torque through the column to the mounting base during tightening.
The horizontal arm slides inward and outward along its guide, allowing the operator to position the tool within the specified working radius. This direct linear movement avoids the folding motion used by a dual-axis arm.
The complete arm assembly rotates around the vertical column, allowing the tool to reach fastening points throughout the surrounding work area while the mounting base remains fixed.
The adjustable spring balancer compensates for the weight of the tightening tool and moving arm components, reducing the load the operator must support. During tightening, the rigid arm transfers reaction torque through the column to the mounting base.
Choose the Right KR001 Configuration
The KR001 Direct-Push Torque Reaction Arm is available in three configurations: KR001-PN without position detection, KR001-PM with XY detection, and KR001-PMZ with XYZ detection. Select the configuration according to whether the workstation requires mechanical tool support only or also needs position data for fastening-point verification. All three configurations are available with 25, 50, or 100 Nm torque ratings.
No Position Detection
For workstations that need tool-weight support and a rigid arm to counteract reaction torque, but do not require fastening-position data.
XY Position Detection
Provides X- and Y-axis position data for distinguishing fastening points across the horizontal working area.
XYZ Position Detection
Adds Z-axis position data to the XY configuration for applications with fastening points located at different horizontal positions and heights.
For KR001-PM and KR001-PMZ configurations, position verification and tightening-sequence functions require a compatible controller or integration with the workstation control system.

Frequently Asked Questions About the KR001 Direct-Push Torque Reaction Arm
Find answers to common questions about torque ratings, tool compatibility, customization, mounting, and model selection.
What applications is the KR001 suitable for?
The KR001 is designed for fixed industrial tightening stations where operators need to guide a supported tool across a defined working area while controlling reaction torque. It is suitable for repetitive assembly tasks within the selected torque rating and working range.
Which torque ratings are available for the KR001?
Standard KR001 configurations are available with torque ratings of 25 Nm, 50 Nm, and 100 Nm. Selection should be based on the tool’s maximum output torque, tool and accessory weight, working radius, and operating conditions. KURAN should confirm the final rating before ordering.
Can the column length and arm length be customized?
Yes. The column length and arm length can be adapted to the workstation height, fastening-point coverage, and available installation space. The required working radius and surrounding clearance should be provided so that KURAN can prepare and confirm the final installation drawing.
Can the KR001 be installed using top or side mounting?
Top- and side-mounted arrangements are available on request for workstations where standard mounting is unsuitable. The mounting direction, available support surface, installation space, and required hole pattern should be confirmed during selection.
Is the KR001 compatible with different tightening tools?
The KR001 can be adapted to various electric and pneumatic tightening tools. Please provide the tool model, dimensions, output type, total weight, and details of sockets, cables, or other accessories so that KURAN can confirm the appropriate tool holder or adapter.
Can position detection be added to the KR001?
Position detection can be included according to the selected configuration. Depending on the application, the system can be supplied without detection or configured for XY or XYZ position detection. When integrated with a compatible controller, position data can support fastening-point verification and error-proofing.
What information is required to select the correct configuration?
Please provide the tool model, maximum torque, total tool weight, nearest and farthest fastening points, required working radius, mounting position, installation direction, available space, and position-detection requirements.
