Information

2025 Steelwrist Rotor Couplers XR XR7 S40

Tilt- and Rotor Coupler

Rotor couplers for excavators between 4 and 20 tonnes

Steelwrist rotor couplers bring a new level of versatility and precision compared to a standard coupler. The flexibility provided by the XR rotor couplers makes your excavator able to take on a variety of tasks, maximizing the utilization of the machine. Designed to perform, our robust gearbox allows for precise and efficient rotation of any work tool. With 360° full rotation freedom you get maximum manoeuvrability and effectiveness.

Excavators equipped with rotor couplers become more versatile machines that can easily change work tools for digging, lifting, crushing or using a grapple, making them suitable for a broad range of applications in construction, demolition, landscaping, and more.

Compact design and easy installation

The Steelwrist rotor coupler has a robust design and still a low building height and weight. Installation is fast and easy as no separate control system is required. The machine needs to be equipped with minimum one dual connection auxiliary line, and an additional auxiliary line can be used to operate the gripper unit (option) or a hydraulic work tool under the rotor coupler.

Modular design for upgrade to SQ/Open-S

The XR20 rotor coupler is available with interfaces following the symmetrical standard (S standard), which is the fastest growing standard internationally. Thanks to the modular design it is possible to upgrade the rotor coupler from S-type to SQ-type. Steelwrist SQ is our high performing automatic oil connection technology used to easily change and connect hydraulic work tools on the excavator. Naturally all SQ products comply with the Open-S standard.

High flow swivel joint for enhanced capabilities

Our rotor couplers have high flow swivel joints, enabling the use of high flow-demanding work tools such as hydraulic breakers, compactors and grapples. The high flow swivel design ensures maximum flow efficiency, allowing your work tools to perform at their best.

Innovative LockSense safety technology

The XR20 comes equipped with our patented LockSense technology, an advanced sensor based system to indicate if the work tool is securely locked. This technology provides a robust and secure solution for safe work tool changes, compliant with safety regulations.
