The AMLOK RLN Series delivers reliable pneumatic rod locking designed specifically for NFPA-standard (inch-sized) pneumatic cylinders. Utilizing a robust spring-engaged, air-released mechanism, the RLN automatically clamps the cylinder rod in the event of air pressure loss, ensuring safety and precision positioning without drift or unintended movement.
| Key Features | |
| Instant, Precision Locking | Holds rod position within 0.002–0.003″ and engages in approximately 100 milliseconds. |
| Fail-Safe Operation | Spring-driven clamp automatically engages if air pressure is lost, ensuring safety. |
| Dual-Directional Force | Provides consistent holding in both push and pull directions. |
| Compact NFPA Integration | Mounts directly onto standard NFPA cylinders—no extensive modifications required. |
| Durable Construction | One-piece, industrial-grade housing designed for long-lasting reliability. |
For applications with potential personal injury risks, consult our engineers about SITEMA safety devices.
The RLN Series is utilized in a breadth of pneumatic cylinder applications, particularly in North America where NFPA-standard cylinders are prevalent. Examples include:
| Applications |
| Automotive Assembly & Machinery |
| Manufacturing Presses (Air-Powered) |
| Packaging & Processing Equipment |
| Robotics & Gantry Systems |
| Woodworking and Glass Machinery |
| Elevating Work Platforms (Air Lifted) |
| General Industrial Machinery |
The RLN provides peace of mind for any inch-standard pneumatic system where uncontrolled movement must be prevented. Its automatic engagement on pressure loss makes it a smart safety upgrade or design inclusion for a vast array of equipment.
The RLN Series employs a robust spring-driven clamping mechanism to automatically secure the cylinder rod upon loss of pneumatic pressure. A built-in pneumatic piston releases the clamp when air pressure returns, delivering consistent, fail-safe holding with minimal backlash. Designed specifically for NFPA-standard pneumatic cylinders, the RLN provides reliable safety and precise positioning control.
Note: The RLI and RLN series share similar options and internal components. The key difference is their mounting interface—RLI is designed for metric cylinders, while RLN fits inch-standard NFPA cylinders.
You can configure the RLN Series rod locks with optional features to meet special requirements:
For enhanced corrosion resistance, RLN locks can be made with stainless steel components or given a nickel-plated finish. These options are ideal for outdoor use or corrosive environments where standard steel might degrade.
Viton seals (and other specialized seal materials) are available for higher temperature operation or exposure to chemicals that might attack standard seals. This ensures the lock maintains performance in extreme conditions.
Wipers/Scrapers can be installed on the rod entry points to keep contaminants out, particularly useful in abrasive dust or slurry environments. Additionally, a fully sealed variant can be provided for applications like food processing or pharmaceutical manufacturing, where ingress of contaminants or washdown fluids must be prevented.
WESTEC 2025 is the West Coast’s leading manufacturing event, bringing together forward-thinking engineers, manufacturers, and solution providers to explore what’s next in precision production. Hennig and Advanced Machine & Engineering (AME) will once again be sharing a booth, offering a hands-on look into integrated solutions that improve uptime, accuracy, and throughput.
Hennig ranked No. 61 among all U.S. manufacturing companies, placing it among the top-performing industrial suppliers in the nation. With estimated 2024 revenues between $100 million and $250 million, the company's trajectory underscores how U.S.-built systems power the next era of industry.
Hennig offers a bellow cover product range that runs the gamut to include covers for dust protection, sophisticated designs featuring extensions and/or lamellas, as well as designs for laser machines.
Both Hennig and its sister company, Advanced Machine & Engineering, now operate under the Hennig brand.
Same team. Same products. Same company. Different look.
Unifying the two brands under one name clarifies our offerings and makes them easier for you to navigate — one website, one team, one trusted partner.
