WP-Series, Collet-Lok® Design Swing Cylinders

  • Collet-Lok® design swing cylinders are ideal when live hydraulics are not available. Clamping is maintained mechanically so live hydraulics are not required during the machining cycle.
  • Double acting Collet-Lok® action allows fully automated operation
  • Additional level of safety since live hydraulics are not required to maintain clamping force
  • Collet-Lok® swing cylinders can be mounted by the flange or threaded into the fixture. Flanged models have manifold ports and tubing ports.
  • Viton seals are standard
