Norgren RT/57308/MC/25 Roundline single acting cylinder - Magnetic
Part Number: RT/57308/MC/25
Quick Summary
Norgren RT/57308/MC/25 Roundline single acting cylinder delivers compact, reliable linear actuation for automation, packaging, and small assembly lines. When space is at a premium or downtime is costly, a high performance solution that fits tight envelopes and requires minimal maintenance makes a difference. Note that for safety critical deployments you may require CE marking, IP protection levels, or SIL ratings—verify against the official datasheet and local regulations. This model uses a low friction seal for long life, a standard magnetic piston for versatile control, and a stainless steel barrel and rod to withstand demanding environments, offering space saving benefits and predictable, repeatable performance in pneumatic systems.

FAQs
Install with the cylinder oriented to minimize side loading, connect the M3 port to a clean compressed air supply within 3 to 10 bar, and secure the end caps per the manufacturer guidelines. Use appropriate mounting brackets to avoid misalignment, and ensure the piston moves freely with buffer cushioning engaged to prevent impact loads.
Key specs include 8 mm bore, 25 mm stroke, M3 port, single acting operation, magnetic piston, buffer cushioning, stainless steel barrel and rod, 3–10 bar operating pressure, -10 to 80 C temperature range, and a theoretical force of 18.6 N.
Yes. The combination of buffer cushioning, stainless steel components, and a magnetic piston provides durable, repeatable actuation with reduced shock loads. Its compact Roundline design also enables tighter layouts, contributing to higher line density and lower downtime in high cycle packaging applications.
The provided data does not specify exact certifications. Commonly required are CE markings and appropriate IP ratings; SIL ratings may apply in safety-critical environments. Verify with the official Norgren datasheet or local regulatory requirements to ensure compliance for your application.
Maintenance is minimized by the long life seals and stainless steel components, reducing lubrication needs and wear. ROI comes from space savings, lower downtime, and easier retrofit with existing control systems, delivering reliable actuation and predictable performance over extended service intervals.
