Palm coupling refers to a type of mechanical joint

Palm coupling refers to a type of mechanical joint that is designed to connect two shafts together. This type of coupling typically consists of two semi-circular flanges, one mounted on each shaft, that are connected by a number of small steel pins. The flanges are usually made of steel or aluminum, and the pins are typically made of stainless steel. Palm couplings are used in a wide variety of applications, including industrial machinery, power transmission systems, and automotive drivetrains. They are known for their high strength and durability, as well as their ability to transmit large amounts of torque.
