Feature → Business Impact → Application: One third the basic length of ISO/VDMA models frees valuable machine space, enabling higher-density layouts and simpler retrofits on existing lines. This compact footprint translates to shorter installation times and reduced enclosure requirements, especially in robotics or pick-and-place stations where clearance is critical. Feature → Business Impact → Application: Low friction, long-life sealing reduces maintenance cycles and energy losses, delivering consistent performance in high-cycle applications and minimizing unexpected downtime. Implement this in assembly lines or transfer systems where uptime is paramount. Feature → Business Impact → Application: Fully non-corrodible construction and anodised aluminium barrel with a martensitic stainless-steel rod resist corrosion in demanding environments, extending service intervals and lowering lifecycle costs for washdown or humid plants. Feature → Business Impact → Application: Standard magnetic piston enables straightforward sensing and position feedback, improving control accuracy and integration with PLCs or industrial automation networks across conveyors and tooling stations. Feature → Business Impact → Application: The 50 mm bore and 20 mm stroke, with a 1–10 bar operating window and a theoretical 1178 N force, provide reliable actuation for medium-load tasks, while the G1/8 port supports quick plumbing and modular accessories. Feature → Business Impact → Application: No cushioning is included by default, simplifying maintenance but requiring external impact management in high-speed cycles; users can select cushioning variants if needed for impact control in precision operations. Industry context insight: These attributes align with high-uptime requirements in automotive, packaging, and material handling, where space savings, predictable wear life, and robust sensing directly translate to reduced downtime and faster ROI.

FAQs
RM/92050/N4/20 is designed to minimize footprint while maintaining familiar bore and port options. It uses a standard G1/8 port and common mounting interfaces typical of 50 mm bore cylinders. Always verify your existing mounting plate pattern and stroke length, and consult the datasheet for precise dimensions to ensure seamless integration.
Operating pressure ranges from 1 to 10 bar (14 to 145 psi). Theoretical force reaches 1178 N at nominal high-pressure conditions. For accurate load management, confirm your load profile and friction within the system, and consider external stops or cushioning if your cycle demands controlled deceleration.
The cylinder uses an anodised aluminium barrel and a martensitic stainless steel piston rod with a magnetic piston, offering good durability and corrosion resistance. Check your exact washdown or IP rating requirements in the official datasheet. If IP-rated variants are needed, select the appropriate specification to meet your risk assessment and compliance needs.
G1/8 is a common port size for 50 mm bore cylinders, enabling straightforward plumbing and quick installation. Ensure compatible fittings, protect against backflow, and verify your system pressure ratings. Use appropriate thread sealant and torque per the datasheet to maintain seal integrity and avoid leaks over time.
Low-friction, long-life seals reduce replacement intervals and downtime, supporting a favorable total cost of ownership for medium-cycle automation. The non-corrodible design and magnetic piston facilitate reliable sensing and consistent performance. Plan periodic inspections of the piston rod and seals, and keep a small spare parts kit to minimize downtime when service is required.
