The main function of the ball guardrail is to protect the important working area of the conveyor and prevent the vibration caused by the high-speed operation of the conveyor during the production and transportation process of the production material from scattering to the motor box and stainless steel chain transmission parts, thereby affecting or reducing the transmission performance of the conveyor accessories. In addition, the ball guardrail can also maintain a long service life, saving manufacturers a lot of money on conveyor maintenance. In the curved parts or diversion and confluence parts of various conveying systems, ball guardrails can also be installed on both sides of the conveyor body to play a guiding role, ensuring that the conveyor plays a correct guiding role in the power transmission and ensuring the safe operation of conveying machinery and equipment products.
