Industrial locking assembly coupling with a 5-1/2" outer diameter (OD) and a 3-1/2" inner diameter (ID). This coupling provides a secure locking connection for industrial equipment requiring precise bore sizing and a robust grip. Designed to fit components bored to 5-1/2" OD and 3-1/2" ID, it serves as a direct-fit option for compatible mechanical assemblies in demanding industrial environments.
