Norgren RT/57225/MC/50 Roundline double acting cylinder - 25 mm bore, 50 mm stroke
Part Number: RT/57225/MC/50
Quick Summary
RT/57225/MC/50 Roundline double acting pneumatic cylinder is a compact actuator designed for space-conscious automation in pick-and-place and clamping applications. Engineers often battle footprint constraints and downtime in tight production lines, so a shorter basic length with robust seals matters. Considerations for this class of cylinder include CE compliance, appropriate IP ratings for the environment, and compatibility with SIL-rated safety circuits to safeguard operations. In service, the stainless steel barrel and magnetic piston enable easy sensor integration, high corrosion resistance, and long-term reliability, supporting predictable lifecycle costs and reduced maintenance. Overall, the combination of space savings, durable construction, and magnetic sensing versatility makes it suitable for modern, data-driven manufacturing environments.

FAQs
RT/57225/MC/50 uses a standard Roundline configuration with a 25 mm bore and 50 mm stroke, featuring Rc1/8 port connections and magnetic piston for easy sensing. Mounting can be done via integrated end caps and compatible clevis or flange fittings, enabling straightforward attachment to tooling plates and guide systems without additional adapters. Consider selecting mounting accessories that align with your machine envelope and cycling requirements to minimize alignment issues and maximize repeatability.
The cylinder provides a theoretical force of 294 N and operates across a pressure range of 1 to 10 bar (15 to 145 psi). Its stainless steel construction and buffer cushioning help translate this force consistently across cycles, while maintaining smooth motion across the specified ambient temperature range of -10 to 80 °C. This makes it suitable for medium-load automation tasks with reliable repeatability.
Yes, within the cylinder’s design envelope. The Roundline geometry, buffer cushioning, and magnetic piston support rapid, controlled actuation with reduced impact and wear—key for high-cycle packaging and assembly lines. For optimization, ensure your controller and valve timing are tuned to leverage the cylinder’s linear travel and 50 mm stroke while maintaining smooth deceleration at end-of-stroke.
Key certifications to check include CE marking for EU compliance, appropriate IP protection ratings for the intended environment, and compatibility with SIL-rated safety circuits for integrated safety systems. Although this specification does not list particular certifications, confirming CE compliance, environmental IP ratings, and safety interoperability helps ensure regulatory alignment and reliable, safe operation in industrial settings.
The combination of low-friction seals, a stainless steel barrel and piston rod, and a magnetic piston reduces wear and supports longer service intervals, lowering total cost of ownership. Buffer cushioning reduces impact-related wear on tooling, end caps, and guide surfaces. Combined, these factors translate to lower downtime, more predictable maintenance windows, and improved asset longevity in harsh environments.
