About our Nexsafe® 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.

  • Precision operation maintains accurate positioning
  • Large clamping surface ensures consistent performance
  • Spring-engaged units engage in power-off situations 
  • Sealed to withstand harsh environments
  • Manual release

Nexen’s 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. 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 patented 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 comes standard with each compact unit.

Nexen’s Spring Engaged, Air Released Rod Locks are safety rated to comply with international safety standard ISO 13849-1. Category Level up to 4 and Performance Level up to e, able to be achieved using Nexsafe products in recommended configuration.
