Space-efficient Roundline design yields up to a 20% reduction in footprint versus a basic ISO/VDMA cylinder, enabling denser machine layouts and easier enclosure routing. This translates to higher line density, reduced frame size, and lower material costs over the actuator’s life. Feature: compact geometry → Business Impact: frees up space for additional actuators or sensors → Application: compact pick-and-place cells and tightly spaced packaging lines. Feature: magnetic piston → Business Impact: straightforward sensing and wiring with reed switches or proximity sensors → Application: reliable position feedback in automated assembly. Feature: buffer cushioning → Business Impact: smoother start/stop, reduced mechanical shock, extended seal life → Application: high-cycle transfer tasks with minimized maintenance. Feature: stainless steel barrel and piston rod → Business Impact: superior corrosion resistance and durability under washdown or humid conditions → Application: food & beverage, automotive sub-assembly in tough environments. Feature: operating range 1–10 bar and -10 to 80 °C → Business Impact: broad compatibility across lines and climates → Application: versatile installation across multiple production stages. Feature: Rc1/4 port and Pneufit C fittings compatibility → Business Impact: flexible piping options and faster installation → Application: rapid field upgrades and modular system design. Feature: Theoretical force up to 1178 N → Business Impact: capable of moving moderate loads with precision → Application: clamping, feeding, and transfer tasks on medium-speed lines. The overall design supports easy mounting with standard Roundline accessories and quick sensor integration thanks to the magnetic piston and robust mounting options.

FAQs
The RT/57250/M/80 uses standard Roundline mounting interfaces. For installation, select compatible QM mounting kits (e.g., QM/8040/38 or QM/8040/32 variants) to achieve the correct piston rod alignment and swivel mounting. Use the 1/4 inch Rc port with Pneufit C fittings for clean, quick connections, and ensure the cavity is clean prior to connection to avoid debris ingress. Confirm clearance for the 52.5 mm width and 199 mm length and verify sensor wiring with the magnetic piston option.
The cylinder provides a theoretical force of 1178 N at the specified operating conditions. Load calculations should account for supply pressure (1–10 bar) and the frictional losses in fittings and end caps. For accurate end-user results, reference the datasheet and perform a F = P × A calculation (P in bars converted to force using the bore area) at the exact operating pressure you’ll use in your cycle.
Yes, its 50 mm bore and 80 mm stroke provide a compact yet capable actuator for pick-and-place tasks in tightly spaced packaging cells. The magnetic piston enables straightforward sensor feedback, and buffer cushioning minimizes impact, contributing to reliable cycling in high-speed lines. For best results, combine with appropriate end-m mounting options and suitable control electronics.
The provided data references typical industry standards such as CE compliance and general safety compatibility with standard control systems. Specific SIL, IP, or further certification details are not listed in the data; confirm with the datasheet or the supplier for your exact regulatory needs. If your application requires SIL-rated safety functions or IP-rated enclosures, consult Norgren technical support to verify suitability and any required accessories.
The Roundline design uses a stainless steel barrel and piston rod with long-life seals and buffer cushioning to minimize wear. Regular maintenance should include checking for seal wear, ensuring clean ports and fittings, and inspecting the magnetic switch harness if installed. The 20% space-saving design also simplifies enclosure maintenance by reducing clutter, while the magnetic piston and robust mounting options promote consistent uptime in medium-duty, high-cycle environments.
