Numatics Rod Lock Units are often used to hold a cylinder load stationary during Emergency Stop (E- Stop) conditions. They are also designed to mechanically lock a cylinder piston rod in the event of an air supply failure. Use caution when applying a Rod Lock unit. The Rod Lock should not be used to "brake" the cylinder piston rod in dynamic conditions. Aditionally, the lock must only be applied when movement has ceased.

We offer two different Rod Locking Units. The NU Lock Series and the RL Series. Both units can be used with our NFPA Interchange cylinder line (A Series) as well as with our ISO 6431 and VDMA 24562 cylinder line.
