Damper Characteristics

  1. Temperature characteristics
    Damper characteristics vary according to the ambient temperature. In general, the damper characteristics become weaker as the temperature increases, and become stronger as the temperature decreases. This is because the viscosity of the oil inside the damper varies according to the temperature. When the temperature returns to normal, the damper characteristics will return to normal as well.

  2. The working angle of the hinge is 120˚.
    Operating the hinge beyond this angle will cause damage to the hinge. Please ensure that an external stopper is in place.
