Feature: 40 mm bore, 10 mm stroke and single-acting operation reduce footprint and inertia, enabling faster cycle times. Business Impact: Frees up constrained mounting spaces while delivering repeatable motion for compact pick-and-place and clamping tasks. Application: Ideal for tight automation lines where space is at a premium and predictable actuation is required. Feature: Low-friction, long-life seal design improves wear performance and minimizes maintenance intervals. Business Impact: Extends service life and reduces downtime costs, improving line throughput. Application: Suitable for high-cycle applications in general pneumatics where reliability matters. Feature: Fully non-corrodible construction with an anodised aluminium barrel and stainless steel piston rod. Business Impact: Withstands harsh or washdown environments, lowering replacement risk and total cost of ownership. Application: Food-grade, pharmaceutical, or moisture-prone settings where corrosion resistance is critical. Feature: Magnetic piston enables straightforward sensing and integration with standard switches (M/50 series). Business Impact: Simplifies control wiring and diagnostics, improving uptime and automation reliability. Application: Sensor-ready for automated lines requiring reliable position feedback. Feature: Compatible fittings and mounting options (G1/8 port, 40 mm bore, QM/90040 series mounts, M/P1501/60 nut, etc.). Business Impact: Quick retrofits and flexible installation across existing infrastructure, reducing project lead times. Application: Retrofit and new-build projects leveraging Pneufit C fittings and standard 40 mm mounting schemes.

FAQs
Mounting choices include BG front/rear flange mounting for 40 mm bore (QM/90040/22) and a foot mounting option (QM/90040/21). Nut-style N2 (M/P1501/60) and stud/adaptor mounting support compatibility with RM/92000/M and RM/91000/M cylinders, enabling flexible installation across new and retrofit projects.
This cylinder operates at 2 to 10 bar with a 40 mm bore and 10 mm stroke. It uses a G1/8 port and operates in a temperature range of -5 to 80 °C. Theoretical force is about 687 N, and materials include an anodised aluminium barrel and austenitic stainless steel piston rod for durability.
Yes. The RM/91040/M/10 is compatible with Magnectic reed switch options, such as M/50 series (5 m cable) and associated switch brackets (M/P72487B). This simplifies integration with control systems and monitoring networks on automation lines.
Pneufit C push-in fittings are available for this family, including 6 mm lines with G1/8 connections. Specific part examples include C0L510618, C02470618, and C02250618, designed for rapid assembly and reliable seals in standard industrial air circuits.
The combination of a low-friction seal design, magnetic piston feedback, and non-corrodible construction reduces maintenance intervals and wear. The 40 mm bore and 10 mm stroke deliver dependable, repeatable actuation in compact footprints, supporting efficient, high-cycle operation on automated lines.
