Quick Summary

RT/57240/MC/125 Roundline cylinder is a compact double-acting pneumatic actuator designed for precise linear motion in automation lines. In constrained panels and crowded machine bays, traditional cylinders often require extra enclosure height and longer lead times. This model uses a stainless steel barrel and piston rod with a standard magnetic piston, delivering reliable sensing and control alongside buffer cushioning for gentle, repeatable stops across 1 to 10 bar air pressure and -10 to 80 °C. The combination of space efficiency, robust materials, and sensor-ready design translates into lower installation costs, easier maintenance, and higher uptime for OEMs and end users.

The RT/57240/MC/125 Roundline cylinder delivers measurable business value through a series of focused features. Space efficiency is achieved with a 40 mm bore and a 125 mm stroke, saving up to 20% in length versus comparable ISO/VDMA cylinders, which reduces panel width and cabinet footprint while enabling higher actuator density on automation lines. The stainless steel barrel and martensitic piston rod provide corrosion resistance and durability in demanding environments, extending service life and lowering lifecycle costs. A standard magnetic piston enables straightforward sensing and integration with existing control systems, improving diagnostics and enabling safer, more predictable operation. Buffer cushioning minimizes impact loads at end positions, reducing wear on seals and frames and enabling higher cycle rates in packaging and pick-and-place tasks. The double crimped end cap design reinforces structural integrity for high-cycle applications and challenging temperature swings, boosting reliability in automotive, food& beverage, and general assembly lines. The RC1/8 port size aligns with common pneumatic manifolds, easing installation and reducing custom fittings. Operating pressure of 1–10 bar and a temperature range of -10 to 80 °C cover typical factory air systems and ambient variations, while the 754 N theoretical force supports mid-load actuation with consistent performance. This cylinder is part of the RT/57200/M Range within Norgren’s Roundline Series, designed for modular automation and easy sensor integration, helping maintenance teams streamline part numbering and stock management. In practice, engineers appreciate the compatibility with standard mounting patterns and quick sensor alignment, which shortens commissioning time and stabilizes production. Overall, the RT/57240/MC/125 delivers a reliable balance of compact footprint, robust materials, sensing-capable design, and predictable actuation for medium-load applications.

FAQs

RT/57240/MC/125 uses a standard Rc1/8 porting pattern, aligning with most common Norgren manifolds and generic pneumatic hardware. Its Roundline mounting footprint simplifies replacement in existing applications, while the magnetic piston supports sensor integration with minimal modification. For upgrades, verify port alignment with your existing manifold gaskets and ensure your control system can read magnetic piston position signals.
The cylinder is designed for operating pressures from 1 to 10 bar and temperatures from -10 to 80 °C. This broad range makes it suitable for typical factory air systems and environments with moderate temperature fluctuations, helping maintain consistent performance across varying production conditions.
Yes. The 40 mm bore with a 125 mm stroke provides a compact, predictable motion profile suitable for fast, repeatable pick-and-place tasks. Buffer cushioning reduces impact at end positions, lowering component wear and enabling higher cycle rates, while the magnetic piston allows easy integration with sensing and control logic for reliable automation.
Choose mounting configurations compatible with roundline actuators, and leverage the stainless steel barrel and piston rod for corrosion resistance in harsher environments. Ensure proper lubrication and avoid side-loading by using appropriate mounting brackets. The 125 mm stroke should be selected to minimize side forces, and frequent inspection of seals and end caps will extend service life in high-cycle setups.
Expect lower lifecycle costs due to the combination of low-friction seals, buffer cushioning, and corrosion-resistant materials that promote longer seal life and fewer replacements. The magnetic piston simplifies diagnostics and spare-part planning, reducing downtime during maintenance windows and enabling faster fault isolation in batch production environments.
