Is the KR001 Dual-Axis Right for Your Workstation?
The KR001 Dual-Axis is intended for tightening workstations with sufficient operating space. Review the following points to determine whether its torque range, working area, load, folding direction, and position-detection options match your application.
Consider the KR001 Dual-Axis When
- Your workstation has sufficient space for a folding-arm structure.
- The required maximum torque is 25, 50, or 100 Nm.
- You need an adjustable working area and spring-balanced tool support.
- The application requires no position detection, XY detection, or XYZ detection.
Confirm These Details Before Selection
- Required default-load configuration: 2.5, 3, or 4 kg.
- Left-folding or right-folding arm configuration.
- Analog 0-10V or RS-485 digital output when position detection is required.
- Tool-handle dimensions, arm length, mounting method, and whether a controller is required.
How the KR001 Dual-Axis Structure Works
The KR001 combines a dual-axis folding arm with a spring balancer. The balancer supports the weight of the tool and arm, while the arm counteracts reaction torque and provides an adjustable working area.
Spring-Balanced Tool Support
The spring balancer supports the combined weight of the tightening tool and arm. Its load can be adjusted for the selected setup.
Dual-Axis Folding Structure
The folding-arm structure provides an adjustable working area and is intended for workstations with sufficient operating space.
Adjustable and Customizable Structure
The horizontal arm and vertical column lengths can be customized, while the cross-arm plate installation position can be adjusted.
Tool-Specific Adapter Block
The adapter block can be customized according to the type and dimensions of the tightening tool handle.

KR001 Position Detection and Configuration Options
The KR001 Dual-Axis is available without position detection or with XY or XYZ position detection. Sensor-equipped models can use analog 0-10V output or RS-485 digital communication, while left- and right-folding configurations are available for different workstation layouts.
Without Position Detection (N)
KR001-FN models are supplied without a position sensor. They are available in 25, 50, and 100 Nm versions with left- or right-folding configurations.
KR001-FN-50R50 Nm, right-folding, without position detection.
XY Position Detection (M)
KR001-FM models provide XY position detection. Select analog 0-10V or RS-485 digital sensor output, together with the required torque and folding direction.
KR001-FM-50LA50 Nm, left-folding, with XY detection and analog 0-10V output.
XYZ Position Detection (MZ)
KR001-FMZ models provide XYZ position detection. They are available with analog 0-10V or RS-485 digital output in 25, 50, and 100 Nm configurations.
KR001-FMZ-50RS50 Nm, right-folding, with XYZ detection and RS-485 digital output.

How the KURAN KR001 Dual-Axis Torque Reaction Arm Works
KR001 Dual-Axis Torque Reaction Arm FAQs
Review common questions about torque capacity, XY and XYZ position detection, folding direction, sensor output, mounting, customization, spring-balancer load, and controller options.
The KR001 Dual-Axis is available in 25 Nm, 50 Nm, and 100 Nm configurations. The selected maximum torque is identified within the product model code.
Yes. KR001-FM models provide XY position detection, while KR001-FMZ models provide XYZ position detection. KR001-FN models are supplied without a position sensor.
Position-detection models can be configured with analog 0-10V output or RS-485 digital communication. In the model code, A represents analog 0-10V and S represents RS-485 digital output.
The folding direction determines how the dual-axis arm folds within the workstation. L identifies a left-folding model and R identifies a right-folding model. Select the direction that matches the workstation layout and available operating space.
The spring balancer supports the combined weight of the tightening tool and arm, and its load can be adjusted for the selected setup. The listed default loads are 2.5 kg for 25 Nm models, 3 kg for 50 Nm models, and 4 kg for 100 Nm models.
The horizontal arm and vertical column lengths can be customized. The installation position of the cross-arm plate is adjustable, and the adapter clamp block can be customized according to the type and dimensions of the tightening tool.
The KR001 Dual-Axis is presented as a desk-mounted torque arm. If your workstation requires a top-mounted or side-mounted configuration, contact KURAN to confirm the installation requirements.
Add the suffix -B01 when the selected configuration is equipped with a controller. For example, KR001-FM-25LA-B01 identifies a 25 Nm, left-folding model with XY position detection, analog 0-10V output, and a controller.
Compare the KR001 Direct-Push type when installation or operating space is limited. The Direct-Push structure requires less space than the Dual-Axis structure.
Configure the KR001 Dual-Axis for Your Workstation
Share your required torque, tightening tool model and handle dimensions, tool weight, working radius, folding direction, mounting method, position-detection requirements, sensor output, and controller needs. KURAN will help confirm the appropriate KR001 Dual-Axis configuration for your workstation.
