1. Speed characteristics: The torque of the rotary buffer changes according to the change of the rotation speed. Torque increases as you go faster, and torque decreases as you go slower. 2. Temperature characteristics: The torque of the rotary buffer also changes according to the change of the ambient temperature. The torque decreases when the ambient temperature increases, and the torque increases when the ambient temperature decreases. This is because the viscosity of the viscous oil changes when the ambient temperature changes. But when the ambient temperature returns to normal temperature, the torque will also return to its original value. 3. Try to keep the minimum gap between the shaft holes during installation. If there is a gap, the buffering effect will be affected.
