AMLOK® rod locks are power-off clamping devices that mount directly to pneumatic or hydraulic actuators (or a separate guide rod) to hold a load securely in place whenever air or hydraulic power is removed or lost. These rod locks automatically grip the cylinder rod to prevent motion—eliminating drift, bounce, or collapse in the event of pressure loss. Designed and built by AME in the USA, AMLOK rod locks put safety, precision, and productivity first by ensuring your machine axes stay exactly where you need them, even during e-stops or power failures. Whether you need to lock a vertical axis for safety or hold a position for machining accuracy, AMLOK solutions provide reliable, easy-to-integrate performance.
Key Features
- Automatic Load Holding | Locks the rod instantly and holds position if system pressure is lost—preventing unintended movement or dropping of the load.
- Direct Cylinder Mounting or Stand-Alone | Attaches directly to standard actuator cylinder interfaces or can be mounted on an independent guide rod for custom applications.
- Mechanical Spring Clamping | Utilizes robust spring-force clamping internally, with pneumatic or hydraulic pressure used to release the lock; this fail-safe design means the default state is locked (intrinsically safe).
- Infinite Position Locking | Capable of clamping at any position along the rod’s stroke (no indexing required), allowing precise positioning and holding at exactly the desired location.
- Dual-Direction Holding | Provides high holding forces in both directions (push or pull) so that the rod is securely clamped against movement in either direction of load.
- Sealed & Customizable Options | Available in sealed versions for washdown, food-grade, or even underwater environments. Custom designs and sizes can be engineered to fit unique applications.
- Made in USA Quality | Engineered and manufactured by Advanced Machine & Engineering, ensuring high-quality materials, strict manufacturing standards, and local support for your AMLOK products.
