63 mm bore compatibility enables direct integration with Norgren's cylinder family, reducing the need for adapters and custom brackets. This tight mechanical fit minimizes misalignment and side loads that degrade performance over time. In high-volume lines, the result is more consistent stroke length, improved repetition, and smoother automation cycles across pick-and-place, gripping, and clamping tasks. The unit is designed for quick changeovers with documented mounting patterns and reusable hardware, cutting downtime during line upgrades or maintenance windows. The locking mechanism provides a positive hold at the end of travel, guarding against drift during high-cycle operation and power-down events. This stability translates to lower scrap rates and less rework on automated lines, especially in robotics, packaging, and assembly contexts where precision governs throughput. By eliminating end-of-stroke uncertainty, operators gain predictable performance without manual adjustments. Installation is streamlined by the familiar mounting patterns and torque specifications found in the datasheet, enabling faster setup with minimal tooling. Engineers benefit from clear integration guidance, reducing the risk of misalignment or binding. Field teams report shorter commissioning times and consistent results across multiple workstations on a production line. Durable design and robust materials resist wear in demanding environments, extending service life and reducing maintenance cycles. The unit withstands typical factory vibration, temperature variation, and exposure to contaminants common in automation settings. Lower maintenance translates into fewer unplanned interventions and a lower total cost of ownership over the device lifecycle. Compatibility with standard 63 mm bore cylinders allows easy retrofits into existing automation cells and supports future scalability. This flexibility makes the model suitable for clamp fixtures, fastening stations, and press auxiliaries across multiple industries, including automotive, food and beverage, and general manufacturing. With documented interfaces for control logic and safety interlocks, the unit integrates cleanly into PLC-based automation and control networks, improving plant-wide traceability and compliance.

FAQs
QA/8063/59 is designed to mount on standard 63 mm bore cylinders in the Norgren family. Verify bore compatibility with the existing actuator pattern and mounting flange, and use the matching mounting hardware per datasheet. The unit integrates with typical ISO-style end blocks, enabling straightforward retrofit without major rework; consult the datasheet for exact hole spacing.
By mechanically locking the cylinder position at the end of travel, the unit minimizes drift and accidental retraction in high-cycle environments. This improves repeatability, reduces mis-picks, and prevents unintended motion during power down, all of which lower scrap rates and unplanned downtime in automated assembly and packaging lines.
Consider available clearance around the cylinder, mounting surface flatness, and the alignment of the locking mechanism with the piston rod. Use the recommended hardware and adhere to the torque specs in the datasheet to avoid binding. Ensure that the locking unit does not interfere with downstream actuators or sensors.
Look for CE marking for European compliance, IP-rated enclosures for dust and water ingress, and SIL-rating if you operate within safety instrumented functions. The locking unit should be evaluated within your plant's risk assessment and integrated with appropriate guarding and control logic.
Maintenance is minimal with a robust mechanical design; periodic inspection is recommended to verify alignment and mounting integrity. Refer to the datasheet for service intervals, and use the downloadable datasheet for replacement parts, mounting bolts, and torque guidance. This helps extend life and maintain reliability in demanding automation environments.
