Norgren RM/91020/M/15 Pneumatic Cylinder - Magnetic
Part Number: RM/91020/M/15
Quick Summary
Norgren RM/91020/M/15 Pneumatic cylinder provides compact single-acting actuation for automated pick-and-place and inline tooling. When space is at a premium and wear-prone seals threaten uptime, engineers need reliable, low-maintenance solutions that fit tight cavities. In European applications, CE marking is often expected and IP-rated environments are common in rugged automation; this model’s rugged, non-corrodible body, low-friction seals, and magnetic piston help address those needs. The design supports fast, predictable cycles with a theoretical force of 161 N and a 20 mm bore, while the anodised aluminium barrel and stainless steel rod extend service life. For businesses, the combination of compact footprint and durable construction translates to easier installation, reduced maintenance, and lower total cost of ownership in automated lines.

FAQs
RM/91020/M/15 uses a standard M5 port, compatible with many compact manifolds in automation cells. For installation, secure the actuator to a rigid mounting surface, connect a clean, dry air line rated to 2–10 bar, and align the rod with the actuated fixture. If using magnetic sensing, ensure correct piston orientation and provide straightforward feedback wiring.
Key specs include a 20 mm bore, 15 mm stroke, 2–10 bar operating pressure, and a maximum force of about 161 N. The single-acting design with no cushioning yields fast strokes in short-lift applications but requires controlled backpressure to prevent overextension. The magnetic piston allows reliable feedback, and the stainless rod with an anodised barrel improves durability in demanding environments.
Yes, its compact 20 mm bore and 15 mm stroke provide a slim profile ideal for tight automation cells. The one-third length advantage over many ISO/VDMA models reduces enclosure size and installation time, while the magnetic piston simplifies sensing. For high-speed pick-and-place, pair with a suitable control valve and ensure mounting clearance and load direction are optimized.
Certification details are typically listed in the product datasheet or on the supplier’s official page. The RM/91020/M/15 is designed for standard pneumatic operation with common materials, but check the datasheet for CE marking, IP protection, and SIL-related notes specific to your region. Always verify with your compliance team to ensure the exact model version meets regulatory requirements.
Maintenance is reduced by a low-friction seal design and corrosion-resistant materials, extending service life and cutting downtime. The 161 N theoretical force supports consistent actuation with minimal energy waste, translating to lower energy costs in high-cycle lines. Routine checks include port cleanliness, seal wear inspection, and ensuring secure mounting to prevent misalignment.
