Welcome to Linqing Xinshengdi Bearing Co., Ltd.
Copper and gold ore processing requires semi-autogenous (SAG) grinding mills that tumble hundreds of tons of rock continuously. The 200mm bore 30240 bearing provides rigid stabilization for the high-torque pinion shafts driving these giant milling drums. Forged from premium-grade impact steel, it effectively neutralizes the brutal, non-stop shock loads generated by cascading rock masses inside the mill, ensuring steady gear mesh and preventing catastrophic drivetrain shutdowns.
