Gear Couplings

Gear couplings are mechanical devices that transmit torque and rotation between two shafts while accommodating misalignment, making them ideal for heavy-duty industrial applications. They consist of two hubs with external gear teeth and a sleeve with internal gear teeth, providing high torque capacity, durability, and high-speed capabilities. Proper lubrication and maintenance are crucial for the longevity and performance of gear couplings.
