OVERVIEW OF ROD LOCKS

  • Over 180 products for round guide rod and air cylinder applications
  • Tested to 3,000,000 cycles
  • Operates in both directions
  • Mounts in any position
  • Multiple actuation springs for reliable performance and redundancy
  • Large clamping area on the rod distributes the forces over a wider area to reduce rod wear
  • Limited dynamic stopping capacity suitable for infrequent emergency stops
  • Units are stacked for higher holding forces
  • Spring Engaged, 60 psi air released
  • Backlash; 0.000-0.003 (proportional to load)
  • Holding force is greater than the matching cylinder force at 100 psi
  • IP67 certified, dust and water tight

RLSS SERIES FEATURES/BENEFITS..


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 bearings 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 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.
