50 mm bore compatibility and standard mounting interfaces streamline both retrofits and new installations. This feature minimizes engineering effort and lowers modification costs, enabling faster deployment of locking functionality across existing automation cylinders. In packaging and assembly applications, the compact unit fits neatly with standard fixtures, reducing setup time and enabling reliable retention from the first cycle. The result is clearer asset alignment, lower total cost of ownership, and a smoother integration with Norgren ecosystem components. Robust locking mechanism delivers secure piston retention under dynamic load and during maintenance lockouts. This translates to reduced drift, better cycle predictability, and safer operator workflows in high-speed lines such as stamping or packaging. Easy installation with standard foot and through-hole mounting supports quick integration with existing control valves and actuators. The design minimizes tight tolerances and alignment issues, improving first-pass assembly yields and lowering field service time. Durable construction and field-proven reliability extend service life and reduce maintenance costs across automated lines. By consolidating position retention in a single device, teams avoid multiple safety interlocks and wiring complexity, delivering a cleaner, safer control architecture. Industry-wide value is clear: this locking unit supports lean manufacturing by reducing changeover time and enabling safer maintenance in packaging, automotive, and material handling environments. When used with Norgren control components, it contributes to a modular, scalable architecture that speeds deployment across lines and minimizes spare part variety. Operators notice fewer unexpected stops, and maintenance teams benefit from predictable lock timing and easier diagnostics, delivering measurable return on investment over typical automation project lifecycles. Looking ahead, the QA/8050/59 is compatible with standard 50 mm bore cylinders and Norgren accessories, simplifying future upgrades and expansions. Verify mounting patterns and ensure datasheet guidance for torque and seal selection. This approach minimizes risk during retrofit projects and supports ongoing compliance with safety and performance standards in automation and control systems.

FAQs
To install on a 50 mm bore cylinder, align the locking unit with the cylinder axis and secure it using the standard mounting pattern provided by Norgren. Verify correct piston position before applying air pressure, ensure seals are intact, and tighten hardware to the recommended torque in the datasheet. Refer to the datasheet for exact fastening patterns, torque values, and guidance on flow paths.
Expect reliable retention during high cycle rates and controlled unlocks during deliberate actuation. The unit is designed to minimize drift and provide repeatable locking across multiple cycles, improving changeover times and reducing scrap due to mispositioned cylinders in packaging and assembly environments.
CE compliance is supported for appropriate configurations; for IP protection, check the variant directory in the datasheet to confirm enclosure ratings for your environment. Always verify the certifications applicable to your installation and ensure alignment with local safety regulations before deployment.
The device reduces downtime from unintended movement, shortens maintenance lockouts, and lowers spares and repair costs by consolidating position retention into a single device. These factors translate to higher line availability and faster ROI on automation projects, particularly in packaging, automotive, and material handling lines.
QA/8050/59 is designed for seamless integration with Norgren actuators, manifolds, and control valves using standard mounting and interface patterns. It can be wired into existing control architectures, supporting consistent logic across the line. When retrofitting, verify mounting patterns, torque specs, and datasheet guidance to ensure smooth compatibility with your control system.
