Norgren RT/57225/M/320 Roundline Cylinder - Magnetic
Part Number: RT/57225/M/320
Quick Summary
Norgren RT/57225/M/320 Roundline cylinder provides compact, double-acting actuation for precise automation in pick-and-place, clamping, and transfer applications. Engineers often struggle with tight spaces, long install times, and wear-heavy seals in conventional cylinders, which drive maintenance costs and downtime. This design aligns with common industry standards, featuring a magnetic piston for sensor versatility, stainless steel barrel and piston rod for durability, and buffer cushioning to soften impacts. Combined with universal mounting and compatible Pneufit C fittings, it delivers seamless integration and reduced total cost of ownership for automated lines.

FAQs
Begin with the QM universal mounting options for a 25 mm bore, then connect the Rc1/8 port using Pneufit C fittings (6 mm tube option). Use the 6 mm/ R1/8 adapters for a clean, leak-free setup. Follow the manufacturer’s torque guidelines for end caps and verify a secure, square alignment before pressurizing the system.
The cylinder provides a theoretical 294 N force at peak stroke under standard conditions (1–10 bar air). Actual performance depends on supply pressure, load, and backpressure. Its buffering reduces impact during end of stroke, contributing to consistent repeatability and extended seal life in high-cycle applications.
Yes. The Roundline design reduces length compared with a basic ISO/VDMA cylinder, delivering up to 20% space savings. Its compact footprint, combined with modular QM/8025 mounting options and easy Pneufit C fittings, supports quick installation and flexible reconfiguration in compact cells.
Typical pneumatic actuators in this class utilize CE-marked safety and performance standards. For industrial environments, assess compatibility with your control system and enclosure requirements. Always consult the published datasheet for application-specific certifications and ensure conformance to your local regulations and safety programs.
You gain from space savings, reduced downtimes due to robust seals and long-life operation, and easier installation with universal mountings and standard Pneufit C fittings. Over multiple cycles, these advantages translate to higher line uptime, lower maintenance costs, and quicker line changeovers in high-usage automation cells.
