Nexen's new generation of linear holding / locking devices 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.
Precision Operation Maintains Accurate Positioning
The RLSS series of Rod Locks guarantees accurate positioning and provides precision holding while other operations are performed. The Rod Lock engages without causing any rod displacement, and also features extremely low backlash making them ideal for precision applications.
Large Clamping Surface Ensures Consistent Performance
The RLSS line is designed with a large clamping surface that provides uniform force to the rod contact area on every engagement. The clamping mechanism utilizes numerous ball bearing to reduce friction.
Spring-engaged Units Engage in Power-off Situations
Nexen’s Rod Locks are spring-engaged, so they operate even in power-off situations to promote safety for operators and machinery. Multiple springs ensure reliable performance and redundancy. The fast response time of these spring-engaged products also increases positioning accuracy. Nexen’s Rod Locks also feature locking mode sensing capability that allows engagement/disengagement feedback with the use of an optional inductive sensor.
Sealed to Withstand Harsh Environments
Every RLSS Rod Lock is sealed to protect internal components. These seals are designed to withstand even harsh wash-down environments and are IP67 rated (anodized models exceed NEMA 4X rating). Rod Locks are available in natural brushed aluminium or with a black anodized coating.
The cam operated manual release feature mechanically disengages the rod lock with the simple turn of a hex screw using a standard wrench. The default-to-lock function springs back to the engaged position when released.
