Norgren RM/92020/M/85 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92020/M/85
Quick Summary
RM/92020/M/85 is a compact double-acting pneumatic cylinder for precise linear actuation in automation. On busy production lines, space is at a premium, and cycle life matters. The RM/92020/M/85 delivers 20 mm bore and 85 mm stroke with a one‑third reduction in length versus ISO/VDMA equivalents. Its magnetic piston and non‑corrodible construction support reliable sensing and long service life in demanding environments. Designed for compatibility with standard control systems, it helps reduce maintenance costs while boosting line uptime. With a compact footprint and a rugged aluminium barrel, it integrates quickly, lowering installation time and risk. This makes it suitable for medical device assembly lines, packaging, tool actuators, and other automated processes.

Feature → Business Impact → Application: The RM/92020/M/85 uses a 20 mm bore with an 85 mm stroke to deliver precise motion in constrained spaces, enabling higher line density without sacrificing reach. This space-optimized form factor reduces machine footprint and simplifies enclosure design, accelerating time to first run and lowering capital expenditure for new lines. The magnetic piston enables straightforward sensor integration, improving feedback accuracy and diagnostic capabilities for PLC-based control and condition monitoring across packaging, material handling, and assembly cells. The anodised aluminium barrel and stainless steel piston rod deliver corrosion resistance and long-term reliability, translating to reduced maintenance cycles, lower replacement costs, and steadier performance in damp or dusty factory environments. Operating from 1 to 10 bar and within -5 to 80 °C, it offers broad air-system compatibility and stable actuation in fluctuating plant conditions. No cushioning inside the unit means end-of-stroke behavior must be managed with external control strategies, but this also provides a cleaner, more predictable force profile for high-speed indexing. Finally, its RM/92000/M range compatibility ensures easy integration with existing Norgren actuation platforms, reducing spare parts complexity and supplier touchpoints.
