Norgren RM/91050/N2/25 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/91050/N2/25
Quick Summary
Norgren RM/91050/N2/25 is a compact single-acting pneumatic cylinder designed for precise linear actuation in automation lines. Engineers often face space constraints, high friction seals, and corrosion risks that drive maintenance. Certifications like CE, IP, and SIL aren’t listed here, but the non-corrodible construction and magnetic piston support reliable operation in rugged industrial environments, while the short length improves machine density. This design delivers a small footprint with robust sensing compatibility, reducing machine footprint and enabling smoother integration with control systems.

FAQs
For installation, ensure proper mounting alignment to prevent side loads on the 50 mm bore cylinder. Use compatible mounting brackets and keep the G1/8 port unobstructed to maintain consistent air flow. Verify that supply pressure remains within 2 to 10 bar and that plumbing uses appropriate seals to avoid leaks. Consider downstream misalignment and cable routing to protect sensing elements from knock or vibration.
The cylinder operates at 2 to 10 bar and withstands temperatures from -5 to 80 °C. It delivers a theoretical force of 1094 N at full stroke for reliable actuation in medium-duty applications, with a 50 mm bore and 25 mm stroke ensuring predictable performance across cycles.
The unit uses a non-corrodible construction with a stainless steel piston rod and an anodised aluminium barrel, which improves durability in many harsh environments. While explicit IP ratings aren’t listed here, the materials choice supports resistance to corrosion in typical factory settings. For washdown or aggressive chemicals, confirm environmental ratings in the official datasheet before deployment.
Yes, the RM/91050/N2/25 features a magnetic piston, enabling straightforward piston position sensing integrated with standard sensors and control logic. This simplifies feedback loops, reduces misalignment risks, and supports reliable automation sequencing in compact spaces.
The design is one-third the basic length of typical ISO/VDMA cylinders, delivering far greater installation density. This enables higher equipment packing and easier retrofitting into existing lines, while preserving the necessary stroke and force characteristics for many medium-duty tasks in packaging, assembly, and fixture applications.
