Rod Locks

Nexen’s Static Rod Locks deliver precision holding with virtually no backlash, providing high accuracy in demanding applications. These spring-engaged, air-released units come in both ISO and NFPA sizes and will accept standard accessories.

The Rod Lock’s large clamping surface ensures high clamping/holding force, and Nexen offers models for use on a pneumatic cylinder or as a stand-alone unit on a guide rod. Customers can further increase holding forces by stacking multiple Rod Locks together. The design is sealed and features a natural brushed aluminum finish or a corrosion-resistant, anodized finish suitable for food/washdown applications. Whatever the application, precision operation with hassle-free performance comes standard with each compact unit.

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 with the rod and features extremely low backlash, making them ideal for precision applications.

Large Clamping Surface
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 features a locking mode sensing capability that allows engagement/disengagement feedback with the use of an optional inductive sensor.

Operating Mode Sensors
The Operating Mode Sensor(s) can be used to signal the engagement or disengagement of the rod lock on the shaft. In an effort to give the system manufacturer the most versatility, the Operating Mode Sensors can be set up as Engagement or Disengagement and either redundant or individual states. Sensors ordered separately are available in both PNP and NPN modes.

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 aluminum or with a black anodized coating.

Manual Release
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.
