  • High-precision & non-backlash
    Even after repeated trips, the load fluctuations are always within ±15%. High rigidity to axial loads eliminates backlash in a connected state.
  • Easy load adjustment & installation
    The trip load can be freely adjusted by simply turning the adjusting screw. The end faces of the case and slide shaft have tap holes for easy installation.
  • Release type
    When overload occurs, the Axial Guard immediately trips and the connection is shut off, so the thrust at the drive side does not transmit. Can be easily reset as the load required for resetting is small.
