Rotary damper gear/plastic damper gear TRD-TE8? ?Damper Characteristicstorque vs angular speed(at room temperature:23℃)?oil damper torque changing by rotate speed as shown in the left drawing. Torque increase by rotate speed increasing.torque vs temperature(rotation speed:20r/min)oil damper torque changing by temperature,generally Torque is increasing when temperature reduction and decreasing when temperature increment.Damper SpecificationTorque0.20.2±0.05 cN·m0.30.3±0.05 cN·m0.40.4±0.06 cN·m0.550.55±0.07 cN·m0.70.7±0.08 cN·m0.850.85±0.09 cN·m1.01.0±0.1 cN·m1.41.4±0.13 cN·m1.81.8±0.18 cN·mXCustomizedMaterialbasePCRotorPOMcoverPCGearPOMO-RingSilicon rubberFluidSilicon oilDurabilityTemperatureRoom Temperature:23℃One cycle→1.5 way clockwise,(90r/min)→1 way anticlockwise(90r/min)Lifetime50000 cycles http://www.toyoudamper.com/rota...plastic-gear-damper.html
