FAQs
The RM/92020/N2/20 uses a standard M5 port and is compatible with Norgren mounting accessories designed for compact 20 mm bore cylinders. When selecting end-mcaps and flange mounts, verify clearances around the 20 mm stroke and ensure sensor wiring does not interfere with the magnetic piston. For quickest setup, use matched Norgren mounting kits and preconfigured manifolds to maintain consistent alignment and stroke repeatability.
Theoretical force is 188 N at rated conditions; the actual output scales with supply pressure within the 1–10 bar range. At 1 bar the force will be proportionally lower, while at 10 bar you approach the full 188 N. For precise force curves in your application, consult the datasheet and perform a live pressure test to account for your load profile and system friction.
This model is a compact, double-acting cylinder with no cushioning, optimized for compact space and reliable performance rather than soft-start cushioning. For high-speed cycles, ensure the system’s supply pressure and pilot hardware support rapid actuation without overshoot. If cushioning or adjustable damping is needed, consider alternative models or add-on cushions, while maintaining alignment with the magnetic sensing and control strategy.
The barrel is made from anodised aluminium alloy and the piston rod from stainless steel (austenitic), with a magnetic piston. These materials provide excellent corrosion resistance and mechanical strength, reducing wear in challenging environments. The design is intended to withstand repetitive cycling, enabling longer maintenance intervals and more predictable performance in automation cells.
