Advanced Machine & Engineering Announces the Fourth-Generation RLI Rod Locks

Advanced Machine & Engineering Co. (AME), Rockford, Ill., introduces the fourth-generation RLI Series rod locks. The new pneumatic series RLI (ISO 6431) metric rod lock has been developed as a solution to control problems inherent to pneumatics—over travel, drifting, bouncing, and reverse traveling. The AMLOK Power-Off rod lock can be mounted to a cylinder, or as a standalone unit.


The patented AMLOK Type RLI is constructed of black anodized aluminum housing with a special piston and wedge locking mechanism actuated by multiple springs that mechanically lock the rod quickly and securely. The clamp is unlocked when air actuates the piston, compresses the spring and releases the locking device. 


  • No rod displacement on engagement
  • Large clamping surface reduces pressure-per-square-inch on the rod, extending service life
  • Fast response time
  • Low backlash
  • 4 bar (60 psi) release pressure
  • Precision holding 0.002”-0.003”
  • Consistent clamping force in both directions
  • High cycle rates and accuracy
  • Holds load during power/pressure loss
  • Compact unit, easy integration
  • Versatile through hole tie rod mounting to ISO 6431 style pneumatic cylinders
  • Many NFPA style-mounting attachments available for stand alone applications


The optional sealed RLI Series design is suitable for food and wash down applications as well as pneumatic and hydraulic presses, scissor-lift tables, test and positioning equipment, amusement ride equipment, printing and paper handling equipment, theatrical equipment (platforms), assembly equipment, and machine tool applications.
