FAQs
The RT/57225/MC/25 uses the Roundline design with standard 25 mm bore and Rc1/8 porting, which aligns with common mounting patterns and accessory kits. It supports typical end-cap configurations and mounting feet used in ISO/VDMA-compatible assemblies. For retrofit projects, verify your current mounting plates and end-stop clearances against the cylinder’s 25 mm stroke and 25 mm bore to ensure seamless integration.
This cylinder operates from 1 to 10 bar (15 to 145 psi) and tolerates temperatures from -10 to 80 °C (14 to 176 °F). These limits enable use in a wide range of automation environments, including standard manufacturing lines and moderate washdown areas, while preserving seal life and actuation accuracy under typical cycling conditions.
Yes, the design, including buffer cushioning and magnetic piston, supports high-cycle operation with smoother deceleration and reduced impact. Routine maintenance includes inspecting seals for wear, checking port connections for leaks, and ensuring the magnetic piston remains clean for reliable sensor feedback. Use clean, dry compressed air and replace seals per schedule to sustain performance.
The magnetic piston enables straightforward non-contact sensing and easy integration with common automation controls, reducing wiring complexity and minimizing installation time. This feature improves positional feedback accuracy, supports higher repeatability in pick-and-place tasks, and simplifies diagnostic workflows across automated lines.
A 25 mm bore provides a theoretical force of approximately 294 N, supporting reliable actuation for small parts and clamping tasks. The 25 mm stroke offers precise, repeatable travel for consistent part handling. When combined with buffer cushioning and double-acting actuation, you get controlled speeds and smoother end-of-stroke behavior, enhancing cycle accuracy and reducing mechanical stress.
