Norgren RT/57250/M/10 Roundline Cylinder - 50mm
Part Number: RT/57250/M/10
Quick Summary
Norgren RT/57250/M/10 is a roundline double-acting cylinder designed for precise pneumatic actuation in tight-space automation. Engineers often face mounting constraints and retrofit challenges when upgrading legacy ISO/VDMA cylinders. The cylinder is CE-compliant and suitable for integration with SIL- and IP-rated control environments where required. Its stainless steel barrel and piston rod provide corrosion resistance in damp or washdown-friendly settings. With a 50 mm diameter and a 10 mm stroke, it delivers predictable force (1178 N) in compact form, reducing footprint without sacrificing control. This makes it a cost-effective choice for automation lines seeking improved performance, easier installation, and longer service intervals.

Compact Roundline design reduces installation length and saves space compared with basic ISO/VDMA cylinders, giving engineers freedom to optimize layouts and reduce machine footprint. The design saves up to 20% space on the basic length, enabling easier retrofits in dense installations and shorter cycle times. Low friction, long-life seals minimize maintenance needs and extend service intervals in high-cycle environments, lowering total cost of ownership. A standard magnetic piston enables straightforward feedback for position sensing and closed-loop control, improving repeatability and automation reliability. Buffer cushioning at stroke end protects adjacent components and reduces mechanical shock, supporting longer life of end stops, mounts, and guide rails. Stainless steel barrel and piston rod deliver corrosion resistance in damp or washdown environments, increasing uptime in demanding industries. Rc1/4 porting and a 1–10 bar operating window provide versatile compatibility with standard air systems, while -10 to 80 °C operating temperature ensures reliability across typical plant conditions. The RT/57250/M range benefits from Norgren’s Roundline family compatibility, simplifying spare-part sourcing and upgrades across batches and lines.

FAQs
RT/57250/M/10 uses standard roundline end-cap mounting and a 50 mm bore, with Rc1/4 ports for compatibility with common air fittings. For installation, align the piston rod axis to avoid side loads and use appropriate mounting brackets or clevis pins. The magnetic piston variant supports straightforward sensor placement, and the long-life seals reduce maintenance during high-cycle operation.
Key specs include a 50 mm bore and 10 mm stroke, Rc1/4 ports, 1–10 bar operating pressure, -10 to 80 °C ambient range, and 1178 N theoretical force. The cylinder is double-acting with buffer cushioning and a magnetic piston for reliable sensing. These factors influence cycle time, repeatability, and integration with existing control systems.
Yes, its low-friction seals and durable stainless steel components minimize wear in high-cycle cycles. The magnetic piston enables direct feedback for closed-loop control, supporting consistent repeatability in packaging and transfer tasks. Buffer cushioning also reduces impact on end stops, enhancing reliability during rapid cycling and frequent position changes.
The product is designed to meet CE safety standards for European installations. For SIL-rated or IP-rated system requirements, verify with your supplier for available variants and regional approvals.
