Damping (or dampening) means that a mechanism will allow for a slow/soft and final close of a given lid, door, arm or other moving component attached to a main body. Damping is not intended and should not be used for position control but rather is a braking mechanism for the natural falling motion due to gravity.
The rotary damper torque changes as per the surrounding temperatures owing to the thickness of the oil depending upon various temperatures.
adjustable rotary damper has been designed for use in various applications where the torque is strong and slow closing of the cover is allowed. The horizontal cover generates the highest and the vertical cover produces the lowest torque.
A satisfactory closing action is not given by the damper when the torque is strong and proper closing of the cover is difficult.
The rotary dampers have torque determined at 23#730; C /- 2#730; C. FYN-S1 Series dampers are self-compensating, which means they can adjust and continue the same action according to load changes. Depending on ambient temperature, the torque will vary. The chart shows the changes of torque in relation to temperature change. The reason for this is that temperature gets affected by oil viscosity.
