Space-saving Roundline architecture reduces mounted length by up to 20% compared with a standard ISO/VDMA cylinder, freeing valuable footprint in compact machines and robotics. This translates to faster line changes and safer, denser layouts for pick-and-place and packaging workflows. The magnetic piston enables full control-system versatility, simplifying sensor integration and feedback for automation or PLC interfaces, while buffering minimizes impact and wear during high-cycle operation. The stainless steel barrel and piston rod deliver superior corrosion resistance and longevity in demanding environments, reducing maintenance cycles and replacement costs, especially in wash-down or outdoor settings. Buffer cushioning further enhances durability by smoothing start/stop transitions, protecting mounting points and seals in high-speed cycles. Rc1/8 port fittings and compact weight (0.23 kg) enable quick, tool-free installation and effortless multi-axis mounting with existing Pneufit C accessories. Operating from 1 to 10 bar and -10 to 80 °C, it suits a wide range of plant atmospheres without sacrificing performance. The combination of 25 mm bore and 25 mm stroke provides predictable, repeatable motion for consistent actuation in automation lines, while the Roundline family supports straightforward scalability across production cells.

FAQs
This actuator uses a 25 mm bore and 25 mm stroke with Rc1/8 ports, enabling straightforward integration with standard Pneufit C fittings and 25 mm mounting patterns. For assembly, align the universal QM/8025/32 or clevis mounting options and attach to a compatible support structure. Ensure the magnetic piston is oriented correctly for sensing options and verify the 127.5 mm length to fit your envelope.
The RT/57225/M/25 operates from 1 to 10 bar and handles temperatures from -10 to 80 °C (14 to 176 °F). This makes it suitable for most standard factory air supplies and general automation environments, including light wash-downs when using corrosion-resistant stainless components and proper enclosure protection.
Yes. Its 25 mm bore with a 25 mm stroke provides compact, repeatable actuation ideal for end-of-arm tooling in pick-and-place and clamping applications. The magnetic piston supports feedback integration, while buffer cushioning reduces impact, extending tool life. The stainless steel barrel and rod add durability in continuous-duty cycles common to robotics cells.
The provided data does not specify formal certifications. In practice, roundline pneumatic cylinders from this class typically align with common industry expectations such as CE compliance and related safety standards, and may offer IP-rated variants depending on enclosure and mounting. Confirm with the supplier or datasheet for explicit certification details before rollout in regulated environments.
The stainless steel barrel and piston rod provide enhanced corrosion resistance and structural strength, reducing wear and extending service life in challenging environments. This lowers maintenance frequency and part replacement costs, improving total cost of ownership. Combined with low-friction seals and buffer cushioning, the cylinder offers predictable performance and lower downtime in high-cycle automation.
