This meticulously engineered pulley is crafted from robust, large seamless steel to ensure unparalleled durability and reliability. By employing a state-of-the-art flame cutting machine, we achieve precision cutting of the tube, followed by expertly welding the inner pulley disc using a specialized pulley welding machine. The collaboration of a positioner in welding the pulley sleeve and disc guarantees impeccable alignment. Our large drum lathe is pivotal in processing the external circle, thus assuring that the pulley maintains a consistent thickness and minimal pulsation. Utilizing premium 45# round steel and sleeve, we meticulously process the entire shaft, ensuring impeccable shaft concentricity and minimizing eccentric shaft force, which results in smoother pulley movement. Equipped with superior quality bearings that incorporate a hot charging system and a bearing block with an inner bearing Enlargement Device, the bearings are effortlessly positioned without the risk of damage from impact. For pulleys enduring forces beyond 80KN, we implement specialized stress elimination treatments. Additionally, for belt speeds surpassing 2.5m/s, a comprehensive static balance inspection is conducted to ensure optimal performance. Our production capabilities are remarkably versatile, allowing us to fabricate pulleys of various types, qualities, and standards tailored precisely to meet the unique specifications and requests of our esteemed customers.
