One-third the basic length of ISO/VDMA models reduces the overall footprint, enabling tighter installations and simpler mounting in small automation cells; this compact form factor translates to faster product changeovers and lower enclosure heights in packaging lines. The business impact is clear: higher line density and improved takt times in constrained spaces, with the practical application seen in pick-and-place, valve actuation, and small-assembly tasks. The low friction, long-life seal design minimizes wear and energy loss, increasing cycle life and reducing maintenance intervals in high-frequency applications such as batch packaging and automated inspection stations. This supports a lower cost of ownership and more predictable uptime. The fully non-corrodible specification enhances durability in challenging environments, reducing corrosion-related maintenance and replacement costs; ideal for food-contact, wash-down, or humid manufacturing areas where reliability matters most. The magnetic piston enables straightforward sensing and system integration, allowing seamless feedback for position control and closed-loop automation—beneficial in robotics, linear actuators, and sensor-based automation. The combination of anodised aluminium barrel and stainless steel piston rod provides a robust, corrosion-resistant core suitable for continuous operation, extending service life in demanding plants while maintaining accurate stroke performance. With a 20 mm bore and 20 mm stroke, plus M5 porting, the unit offers a compact footprint and easy compatibility with standard compressed-air lines and mounting accessories, reducing installation time and part variety. Operating from 1 to 10 bar and from -5 to 80 °C, this cylinder supports diverse industrial environments, with a nominal 188 N theoretical force that ensures usable actuation across common automation tasks. Built to perform without cushioning, it delivers a clean, direct stroke with repeatable positioning, minimizing vibration-induced wear and enabling smooth system dynamics.

FAQs
The RM/92020/JM/20 uses an M5 air port and is designed for compact mounting. Ensure compatibility with standard M5 fittings, maintain 1–10 bar supply pressure, and use appropriate mounting brackets to support the 20 mm bore cylinder. The magnetic piston supports reliable sensor integration, so plan for proximity or optical sensors aligned with piston travel for straightforward position feedback.
Key specs include a 20 mm bore, 20 mm stroke, and a theoretical force of 188 N. Operating pressure ranges from 1 to 10 bar and temperature from -5 to 80 °C. The cylinder uses a magnetic piston, with an anodised aluminium barrel and a stainless steel piston rod, offering robust, corrosion-resistant actuation suitable for continuous operation.
Yes. The design features low-friction, long-life seals and a magnetic piston, which collectively reduce wear, enable reliable cycling, and lower maintenance needs in high-frequency pick-and-place or precision actuation tasks. Its compact length also helps maintain performance in densely packed automation lines.
Absolutely. The standard magnetic piston allows easy integration with proximity or reed sensors, enabling reliable position feedback for closed-loop control in automation sequences, robotics, and PLC-based control schemes. This simplifies wiring and improves repeatability of piston position across cycles.
Rely on the non-corrodible construction and no cushioning to minimize maintenance. Follow the datasheet guidance for routine inspections of seals and rod surfaces, keep the air supply clean and dry, and select contemporary sensing options for consistent feedback. The result is extended service life, fewer unscheduled outages, and lower replacement costs in typical production environments.
