Fluid Couplings (40 suppliers)

Fluid couplings are torque-transmitting couplings that use hydraulic oil or water to transmit power. They differ from torque converters in that the input torque is equal to the output torque (no multiplication of torque).

Rigid Couplings (208 suppliers)

Rigid couplings connect rotating members such as shafts. They secure onto both members and provide transmission of torque and motion.
