How to Use the Damper
The damper generates torque in both clockwise and counter-clockwise directions.
A friction-type hinge damper can be used as a bearing.
Friction-type hinge dampers have a long product life and do not require lubrication.
Torque down will result if the damper part gets wet with water or oil.
It cannot be used for continuous rotation. Please use it in a vane motion.
Depending on the operating conditions, it can be used as a free-stop
hinge. Please calculate the retention torque based on the following
equation.
This damper is only for horizontal application. Please do not use this
damper for vertical application.
Damper Characteristics
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 temperature
of the shaft bush inside the damper varies according to the temperature. When
the temperature returns to normal, the damper characteristics will return to
normal as well.
Speed characteristics
The speed characteristics of a friction-type hinge damper are shown in the graph
below. The damper torque is determined based on the speed characteristics at
2rpm.
