FAQs

Installation uses standard 1/4 inch Rc ports and Pneufit C adapters. The model supports 8 mm tubing with R1/4 connections and is compatible with common mounting options (foot, rod clevis, and swivel mounts). When planning retrofits, confirm porting layout, seal clearances, and alignment to avoid side-loading. Always follow the nuts and torque specs in the datasheet.
The RT/57250/M/25 operates from 1 to 10 bar (15 to 145 psi) and withstands temperatures from -10 to 80 °C (14 to 176 °F). When selecting for your process, ensure media quality and ambient conditions meet these limits to maintain seal life and consistent force output.
Yes, it uses a stainless steel (austenitic) barrel and a stainless steel (martensitic) piston rod, enhancing corrosion resistance. While this improves durability in many environments, verify exposure to specific chemicals and washdown cycles, and apply appropriate coatings or protective housings if required by your process.
Best suited for compact pick-and-place, clamping, and sensing actions where space is at a premium. Its magnetic piston supports easy switch integration, while the 50 mm bore and 25 mm stroke deliver reliable force for mid-range tasks in packaging, automation cells, and small robot end-effectors.
The unit features low-friction, long-life seals and buffer cushioning to minimize wear and extend service intervals. Regular inspection of end caps and seals, plus verifying mounting integrity and port cleanliness, helps sustain performance and reduces unplanned downtime, delivering measurable ROI over high-cycle operations.
