Feature → Business Impact → Application: The RT/57225/M/80 uses a 25 mm bore and 80 mm stroke in a Roundline double-acting package, delivering a compact footprint that saves space in crowded machine layouts and reduces overall line height. This translates to faster install times and more room for auxiliary components, improving line throughput in packaging and assembly where space is at a premium. Feature → Business Impact → Application: The stainless steel barrel and martensitic piston rod deliver corrosion resistance and sustained accuracy in harsh environments, lowering maintenance costs and extending service life in food, pharma, and general industrial lines where washdown or chemical exposure is a concern. Feature → Business Impact → Application: Buffer cushioning and a standard magnetic piston enable smooth starts and easy sensor integration for closed-loop control, minimizing vibration and enhancing repeatability in pick-and-place and clamping tasks. Feature → Business Impact → Application: Rc1/8 port size and compatibility with Pneufit C fittings streamline installation, reducing assembly time and enabling straightforward retrofits to existing systems. Feature → Business Impact → Application: Operating -10 to 80 °C and 1 to 10 bar pressure broaden application windows, supporting high-cycle operation from semi-automatic to fully automated lines while maintaining consistent performance. Theoretical force of 294 N provides a reliable push in most standard automation pick-and-place and transfer operations, ensuring compatibility with common grippers and fixtures. Weight of 0.472 kg keeps the unit light enough for rapid billet changes and easy mounting in compact enclosures. Pairing these attributes with the Roundline series reduces total cost of ownership by combining durability, precision, and ease of maintenance across multiple products and platforms.

FAQs

Installation starts with selecting compatible mounting options such as the UF Universal Piston Rod Mounting for 25 mm bore or the F‑Mounting options. Use Rc1/8 port fittings for a clean, leak-free connection and follow the datasheet guidance for correct orientation of the magnetic piston. The included dimensional data (26.5 mm height, 182.5 mm length, 26.5 mm width) helps ensure your brackets and guides align precisely. Consider adding switch proximity sensors like the M/50/LSU series for reliable feedback without interfering with the rod movement.
This cylinder provides a 25 mm bore and 80 mm stroke with a theoretical pushing force of 294 N. It operates from 1 to 10 bar (14.5 to 145 psi) and functions across a temperature range of -10 to 80 °C. The port size is Rc1/8, and the design includes buffer cushioning for smooth operation, making it suitable for high-cycle applications in automation lines where precise, repeatable motion is critical.
Yes, the design emphasizes durability and repeatability for demanding cycles. The buffer cushioning reduces impact and wear, while the stainless steel barrel and piston rod resist corrosion and deformation over time. The magnetic piston enables straightforward sensing for closed-loop control, and the compact Roundline form-factor helps maintain consistent cycle times even in tightly packed equipment environments.
In practice, roundline cylinders like RT/57225/M/80 are selected to support CE safety expectations, SIL-capable control schemes, and IP-rated enclosures where applicable. When specifying this part, verify your system’s compliance requirements and check the complete datasheet for any manufacturer-reported certifications or third-party verifications. If your application requires specific approvals, consult the supplier for a version that meets those standards or request a formal certificate of conformity.
The combination of low-friction seals, stainless steel materials, and a robust end-cap design supports long service intervals and reduced replacement costs. The 20% space savings relative to a basic ISO/VDMA length allows more compact line layouts, potentially lowering installation time and cabling needs. With magnetic sensing and standard fittings, you can lower integration costs and speed up commissioning, contributing to a favorable return on investment through increased uptime and throughput.
