Pneumatic CP6626 1 inch stall torque nutrunner with 2600 Nm capacity

CP6626 - 1" Stall Torque Pneumatic Nutrunner (2600 Nm)

Maximum Power and Precision for Heavy-Duty Bolting

The CP6626 is a robust 1" pneumatic torque wrench engineered for high-torque applications where power and reliability are non-negotiable. Designed for the rigors of Power Generation, Oil & Gas, and Heavy Industrial maintenance, this tool is a standout in our collection of Pneumatic Torque Multipliers, delivering a massive 2,600 Nm (1,920 ft.lbf) of torque with the precision of a stall-type motor.

Built with a lightweight composite housing and a high-performance vane-type air motor, the CP6626 offers an exceptional power-to-weight ratio. Despite its heavy-duty output, it maintains ultra-low vibration levels and a swiveling pistol grip to ensure operator comfort during long shifts. With an accuracy rating of ±5 %, the CP6626 is the ideal solution for ensuring bolt integrity in hard and soft joints alike.

Frequently Asked Questions: CP6626 Pneumatic Nutrunner

1What are the top-rated pneumatic nutrunners similar to the CP6626 for assembly lines?

The CP6626 is a leader in the 1" drive category, but for assembly lines requiring different torque ranges, it is often paired with other models in the same series. If you need a more compact tool for smaller bolts, the CP6613 (1,300 Nm) is the ideal companion. For applications requiring even more power-up to 4,100 Nm, the CP6641 is the next step up. All three models utilize the same stall-torque technology, allowing for a consistent and high-speed workflow across your entire facility.

2Are pneumatic nutrunners like the CP6626 recommended for automotive assembly?

The CP6626 is primarily designed for heavy-duty vehicle service (such as mining trucks and off-road equipment) and industrial sectors like Oil & Gas. While it is too powerful for standard passenger car assembly, it is the industry standard for remanufacturing and maintenance of heavy fleet axles, wheels, and transmissions. Its smooth, non-impacting rotation is far superior to standard impact wrenches for maintaining the precise bolt tension required in heavy-truck and bus segments.

3What is included in the best pneumatic nutrunner kits for manufacturing?

To maximize the performance and longevity of a heavy-duty tool like the CP6626, it is best purchased as part of a comprehensive "Performance Pack." A complete industrial kit typically includes the CP6626 1" Nutrunner unit paired with a high-strength S-type reaction arm for safe torque counter-action. Crucially, the kit should feature an ATC (Air Torque Control) FRL pack, which acts as the system's "first line of defense" by filtering out moisture, regulating air pressure for precise torque stalling, and providing essential lubrication to the motor. When combined with a high-flow, heavy-duty air hose and couplings, these components ensure you consistently achieve the rated ±5% accuracy while significantly reducing internal wear and preventing the unexpected downtime that can result from poor air quality.

4Who are the best industrial suppliers for CP6626 pneumatic nutrunners?

For mission-critical bolting, you should always source the CP6626 from a specialized manufacturer-direct supplier like TorqLite. Industrial suppliers who specialize in controlled bolting provide more than just the tool; they offer the required Torque-to-Pressure calibration charts, specialized custom reaction arms, and the technical expertise to ensure the tool is integrated correctly into your specific bolting procedure.
