Straight Nutrunner QST-CT 2-10,000 Nm

Straight Nutrunner QST-CT 2-10,000 Nm

Straight Nutrunner QST-CT sets the global standard for precision tightening in automated assembly lines and advanced robotic cells. Designed in an Inline configuration, this series provides a compact and smart fastening solution that integrates easily onto robotic arms or fixtured machines, ensuring uncompromising tightening quality.

The QST-CT series offers an extensive torque range of 2 to 10,000 Nm, allowing for the tightening of a vast variety of bolts with an accuracy of +/- 2.5% according to ISO5393. While the standard CT model includes a torque transducer and angle encoder, Atlas Copco also offers redundancy versions for critical applications: QST-CTT models with a double transducer for data verification, and QST-CATT models with both double transducers and double angle encoders for maximum safety. The nutrunners fully interface with Power Focus 6000 and PowerMACS 4000 controllers, support Hot Swap, and are designed to run for one million cycles without maintenance, ensuring maximum operational continuity.

Key Features of Straight Nutrunner QST-CT

• Reliability & Safety (Redundancy): The series includes advanced versions (CTT/CATT) with dual backup systems to prevent errors in “Safety Critical” applications.
• Proven Industrial Precision: A smart nutrunner ensuring minimal torque deviation of +/- 2.5% and full control over rotation angle.
• Simple Integration: The straight Inline configuration saves space and allows for dense installation in Multi-Spindle systems or on robots.
• Durability & Power: Heavy-duty design engineered for continuous operation, with exceptionally long maintenance intervals reducing operating costs.

Frequently Asked Questions

Q: What is the difference between QST-CT, CTT, and CATT models?
A: QST-CT is the standard model. CTT models include an extra torque transducer for dual control. CATT models are the safest, featuring full double backup (transducers and angle encoders) for maximum safety.

Q: Which controllers does the nutrunner connect to?
A: QST-CT nutrunners connect to leading Atlas Copco controllers: Power Focus 6000 and PowerMACS 4000, enabling full data collection and smart line management.
