Handling High Torque and Variable Speeds with Oil Couplings

Oil couplings are well-suited for applications that involve high torque and variable speeds due to their unique design and operating principle. Here’s how they handle these challenges:

  • High Torque: Oil couplings can effectively handle high torque levels by using the fluid’s viscosity and shear properties to transmit torque. As torque increases, the viscosity of the oil also increases, enhancing its ability to transmit power. This characteristic allows oil couplings to withstand sudden spikes in torque without causing damage.
