Cylinders & Actuators - NFPA and ISO Rod Lock - Numatics Series NRL
Rod Lock - 32 to 125mm, 1 1/2 to 8

Numatics new generation of linear holding/locking devices, NRL Series, take rod locking technology to the next level. With superior performance, these spring-engaged, air-released units supplement air cylinders and guide rods for holding in power-off/e-stop situations. High clamping forces ensure positive holding with minimal air required for release. Choose from our standard products, or we will work with you to meet your unique application specifications.

Customers can further increase holding forces by stacking multiple Rod Locks together. The patent pending design is sealed and features a natural brushed aluminum finish or a corrosion-resistant, anodized finish. Whatever your application, precision operation with hassle-free performance come standard with each compact unit.
