Next Generation Pneumatic Rod Lock from AME

Advanced Machine & Engineering Co., (AME) Rockford, IL announces the Fourth- Generation RLN Series Rod Locks. The new Pneumatic Series RLN 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 NFPA cylinder, or as a stand alone unit.

The patented AMLOK® Type RLN 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.

o No rod displacement on engagement

o Large clamping surface reduces pressure-per-square-inch on the rod, extending service life

o Fast response time

o Low backlash

o 4 bar (60 psi) release pressure

o Precision holding 0.002-0.003

o Consistent clamping force in both directions

o High cycle rates and accuracy

o Holds load during power/pressure loss

o Compact unit, easy integration

o Versatile sleeve nut/tie rod mounting to NFPA style pneumatic cylinders

o Many NFPA style-mounting attachments available for stand alone applications

The optional sealed RLN 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.
