Coupling is a vital category in industrial and automation systems, connecting rotating shafts to transmit power efficiently while accommodating misalignment, vibration, and shock absorption. Common types include rigid couplings for precise alignment, flexible couplings for minor misalignments, and fluid couplings for smooth torque transmission. Key products in this category encompass jaw couplings, gear couplings, chain couplings, and grid couplings, each designed for specific applications such as heavy machinery, conveyor systems, and motor-driven equipment. These components ensure reliable power transfer, reduce mechanical stress, and enhance system longevity in demanding industrial environments.
