FAQs
For tight spaces, mount orientation should align with the machine’s axis and available access for maintenance. The 20 mm bore and 40 mm stroke support compact layouts, while the M5 port size simplifies plumbing with standard fittings. The magnetic piston enables straightforward sensor integration, reducing misalignment risks and enabling reliable position feedback in confined setups.
The RM/93020/M/40 operates at 2–10 bar (29–145 psi) of compressed air with a 20 mm bore and a 40 mm stroke. It is a single-acting cylinder suitable for return actuation in automation tasks. These specifications support repeatable motion, predictable force (~119 N theoretical), and straightforward control in compact automation cells.
The unit features an anodised aluminium barrel and a stainless steel piston rod, delivering improved corrosion resistance over basic alloys. While this enhances durability, confirm IP rating and cleansing requirements from the datasheet before washdown use. For exposed environments, consider additional protective housings or coatings as needed.
A magnetic piston provides reliable, contact-free position sensing, enabling clean wiring and error-free feedback to controllers or PLCs. This simplifies sensor selection, reduces mounting tolerance issues, and improves repeatability in critical pick-and-place and clamping applications, especially where compact form factors are required.
The cylinder uses a low-friction, long-life seal design and a robust non-corrodible specification to extend service intervals and reduce downtime. Routine inspection of seals and fasteners, along with moisture-free air supply, will help maintain optimal performance. The combination of materials and design supports consistent actuation over many cycles in industrial environments.
