CSB-PCC® plastic cable drag chain is used in the automatic production line of precision shafts. The lateral travel distance of the manipulator is 25 meters, and it executes more than 2000 cycles per day, and the upper and lower grasping actions exceed 4000 cycles. C03 high load cable chains are used to protect the lateral long-stroke cables of the manipulator; C02 universal cable chains are used to protect the cable of the upper and lower grabbing arms of the manipulator; C01 micro cable chains are applied in automatic bearing conveying line between machining lines and heat treatment process.
