Rod Lock for NC9 & PA-2 Series Cylinders

Brand: Schrader Bellows

The Rod Lock prevents rod movement upon release of stored energy, eliminates the need for pilot operated check valves for load holding, and eliminates complicated piping between pilot operated check valves and the cylinder.
  • Manual override shaft allows release of the Rod Lock independent of pneumatic controls. The override is spring loaded and engages the rod lock when the wrench is removed and the air signal is absent
  • Piston rod extension and Rod Lock pilot conform to NFPA dimensions
  • Fluorocarbon rod wiper cleans rod on retract stroke and excludes contamination from the Rod Lock
  • Light weight aluminum Rod Lock body is anodized for corrosion protection
Features
  • True Bolt-on Modularity – the cylinder is built and tested as a stand alone unit. The Rod Lock is then assembled and tested at rated holding force. 
  • Large Rod Lock Clamping Surface – provides uniform force to the rod contact area. This allows holding forces to resist 100 psi input on the cylinder cap end for most bore and rod combinations. 
  • Spring-engaged, air-released operation – ensures positive holding in power-off situations with minimal air volume required for release. 
  • Manual release is standard – cam operated release disengages the Rod Lock with a simple turn of a hex bolt. The default-to-lock function springs back to the engaged position when released. 
  • Rod Lock is sealed to withstand harsh environments – NEMA 4X rating protects internal components from contamination
