Industrial door garage door coupling

Couplings in industrial doors play a role in connecting two shafts or shafts with rotating parts. They rotate together during the process of transmitting motion and power and do not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected machine parts from bearing excessive loads, playing a role in overload protection.

Couplings are the "connection hubs" of the transmission systems of industrial and garage doors. Through power transmission, deviation compensation, vibration damping and potential overload protection, they ensure the stable, safe and durable operation of the door body. They are one of the key components for industrial doors to achieve automated and efficient operation.
