Feature: 50 mm bore provides a predictable actuation force, improving repeatability of positioning and clamping across stations. Business Impact: this reduces cycle time variation and part misalignment, enabling higher overall equipment effectiveness. Application: ideal for end-of-line packaging, automated assembly, and material handling tasks where precise timing and synchronized movement are critical to throughput. Feature: Rear hinge mounting provides flexible, space-saving installation even in cabinets or panels with limited access. Business Impact: simplifies integration into tight automation cells, lowers mechanical risk from misalignment, reduces maintenance time, and supports easier retrofit projects. Application: retrofits and new lines where panel space and access are constrained, enabling quicker commissioning and cleaner routing of hoses and cables. Feature: Compact envelope (59 mm height, 87 mm length, 54 mm width) enables versatile mounting in confined spaces. Business Impact: supports closer component spacing, shorter actuation paths, and neater wiring. Application: control cabinets, robotics work cells, packaging stations, and other compact automation systems where footprint matters. Feature: Lightweight design at 0.35 kg supports faster actuation, reduced inertia, and less wear on guiding elements and mounts in high-cycle environments. Business Impact: lowers energy consumption, minimizes dynamic load on mounting structures, and extends the lifecycle of the actuator and associated air supply lines. Application: high-frequency indexing, pick-and-place cycles, and dynamic positioning tasks in manufacturing lines. Feature: German engineering heritage via IMI Norgren delivers durability, precision, and consistent performance across production runs. Business Impact: ensures predictable quality, easier procurement planning, and more reliable service intervals, which translates to lower total cost of ownership. Application: critical lines in automotive, packaging, logistics automation, and process control where uptime is essential. Feature: Compatibility with standard mounting patterns and the Norgren accessory ecosystem enables quick integration with existing equipment. Business Impact: reduces engineering time, minimizes spare parts variety, and accelerates rollout across multi-site operations, with fewer configuration errors. Application: multi-vendor automation environments and retrofit projects where standardization drives procurement and maintenance efficiency.

FAQs
To install the QM/55250/24, first verify mounting clearance around the rear-hinged end to ensure full travel without interference. Attach the cylinder using standard mounting holes, align the piston rod with the driven element, and connect air lines with proper anti-kink routing. Ensure seals and fasteners are torqued to specification, then perform a leak check and functional test at low pressure before full production. The rear hinge design facilitates flexible orientation, reducing installation time in constrained spaces.
Actuation force depends on system pressure and piston area. A 50 mm bore has a piston area of about 0.00196 m². At a typical shop pressure of 6 bar (0.6 MPa), the theoretical actuator force is roughly 1.18 kN. Real-world force may vary with temperature, porting losses, and rod end load. Use this as a starting point for system sizing and validate with on-site testing at your operating pressure.
Yes, the QM/55250/24’s compact, 50 mm bore with rear hinge mounting is well-suited for automotive packaging lines and other tight automation cells where space is at a premium. Its IMI Norgren heritage supports durable, consistent performance. Before deployment, confirm CE marking and any site-specific IP or SIL requirements, and ensure compatibility with existing actuation and control architectures.
For regulatory compliance, verify CE marking for EU electrical safety, appropriate IP ratings for environmental protection, and SIL ratings if the cylinder participates in safety-related functions. The QM/55250/24 data does not specify these certs, so confirm with the supplier for your exact installation, especially in process, automotive, or packaging environments that demand stringent safety and reliability standards.
Regular inspection of mounting hardware, seals, and connection fittings minimizes air leaks and wear. The rear hinge mounting simplifies access for inspection and replacement, reducing downtime. Over the lifecycle, the cylinder’s compact footprint and German engineering contribute to lower total cost of ownership through easier procurement, standardized interfaces, and fewer spare-part options, translating to faster maintenance and faster project ROI.
