Norgren RT/57225/MF/125 Roundline Cylinder - 125 mm Stroke
Part Number: RT/57225/MF/125
Quick Summary
Norgren RT/57225/MF/125 Roundline double-acting cylinder delivers compact, precise linear actuation for automation lines and pick-and-place cells. In tight layouts, traditional cylinders can dominate space, hinder accessibility, and slow changeovers. This Roundline model saves critical space by up to 20% over basic ISO/VDMA cylinder length while maintaining robust performance. The design features a standard magnetic piston for seamless integration with position sensing and control hardware, along with buffer cushioning for smoother operation. While the data sheet here does not list explicit certifications, industry practice for this form factor emphasizes CE compliance and IP protection in many environments, with SIL-safe control options in safety-rated systems. This combination lowers total cost of ownership and supports scalable automation across pneumatic systems.
