The RM/960/M/220 uses a tie rod double acting design to deliver precise, high-force actuation across demanding production lines. A 6-inch bore and 220 mm stroke provide substantial travel and push/pull capability, with a theoretical force of 10887 N enabling aggressive material handling. The magnetic piston rod supports simple, non-contact sensing for automation and safety interlocks. The barrel is made from anodised aluminium while the piston rod is stainless steel (martensitic), delivering rugged durability and corrosion resistance in tough environments. The magnetic version enhances sensing options without adding complexity to the actuation mechanism. The unit is designed to tolerate continuous operation across a wide temperature range (-20 to 80 °C) and pressure range (2 to 10 bar). Adjustable cushioning minimizes impact, reduces vibration, and extends seal life, translating to lower maintenance costs and less downtime in high-cycle applications. The G1/2 port size aligns with common pneumatic circuits and standard manifolds, simplifying installation and replacement. The 6-inch bore provides predictable stopping force, improving repeatability in pick-and-place tasks. Numerous mountings are available, offering flexible integration into existing fixtures and minimal rework during line upgrades. The RM/960/M/220 belongs to the RM/900 range within the Martonair family, ensuring compatibility with service kits and spare parts such as QM/960/00 for RM/900, 6-inch cylinders. Magnetic version enables reliable position sensing for PLCs and safety interlocks. Overall, selecting this cylinder supports higher throughput and consistent performance in packaging, machine tending, and general automation. The rugged design reduces unplanned downtime, while the adjustable cushioning and durable materials contribute to a lower total cost of ownership. By aligning with standard components and long-term service support, teams can accelerate installation and maintain compliance across plant operations.

FAQs
Install RM/960/M/220 using standard mounting patterns compatible with RM/900 fixtures. Select the correct end or side mounts for your frame, secure the cylinder, align the bore, and connect a clean G1/2 supply with proper filtration. Verify cushioning is set for your cycle rate and load, then test through a few cycles to confirm alignment and smooth travel.
In high-cycle environments you can rely on a 6-inch bore and 220 mm stroke to deliver strong pushing and pulling force, aided by adjustable cushioning that dampens impact. The magnetic piston simplifies sensing, enabling precise feedback for PLCs. The operating range of 2–10 bar and -20 to 80 °C support consistent performance across typical factory conditions.
Yes. The 6-inch bore and 220 mm stroke provide ample travel and force for packaging and machine tending tasks. The magnetic piston supports sensor-based feedback, while adjustable cushioning helps minimize impact and wear in fast cycles. With standard G1/2 porting and robust construction, it integrates well with common automation rails and fixtures.
The provided data does not list formal certifications. In practice, many industrial pneumatic cylinders in this class rely on CE conformity and IP-rated housings, with SIL safety-compatible controls. Always verify with the datasheet and supplier, and confirm any plant-specific compliance requirements before deployment. Refer to the Datasheet PDF for detailed guidance.
Service kits for RM/960/M/220 are accessible via QM/960/00, which covers RM/900, 6-inch cylinders. These kits facilitate seal, cushion, and accessory replacements to sustain performance. When planning maintenance, pair service kits with the Datasheet and recommended spare parts to minimize downtime and extend the cylinder’s lifecycle.
