FAQs
The RM/92020/JM/50 uses a standard M5 port and a 20 mm bore with a 50 mm stroke, making it compatible with common mounting blocks and end-plates used in compact automation. For fastest integration, pair it with Norgren mounting accessories designed for RM/92000 series and verify your supply is within 1–10 bar of compressed air. Ensure proper alignment and secure mounting to prevent side loading during operation.
The cylinder operates from -5 to 80 °C, suitable for a wide range of industrial environments. The recommended operating pressure is 1 to 10 bar (14 to 145 psi), providing adequate force for typical 20 mm bore applications while maintaining efficient air consumption and cycle stability.
This model has no cushioning. While cushioning is beneficial for soft deceleration and reduced impact, its absence can enable higher-speed actuation and shorter cycle times. If soft stops are required, consider using external cushioning accessories or adjusting control strategies to manage deceleration before end-stroke contact.
The unit provides a theoretical force of 188 N. The barrel is made from anodised aluminium alloy, while the piston rod is stainless steel (austenitic). This combination delivers a robust, corrosion-resistant structure with reliable dynamic performance suitable for demanding industrial tasks.
Yes. The cylinder uses a magnetic piston, enabling straightforward sensing and integration with position detectors, PLCs, and other control systems. This magnetic feature supports clearer feedback signals, simplifies wiring, and enhances control accuracy without needing additional position-sensing hardware in many configurations.
