Crafted with precision and robustness, the pulley is directly fabricated from large seamless steel, ensuring reliability in every aspect. Using advanced flame cutting machines, we achieve meticulous precision in cutting the tube. Our expert pulley welding machines seamlessly weld the inner pulley disc, while the positioner guarantees the precise union of the pulley sleeve and disc. The large drum lathe processes the outer circle, ensuring uniform thickness and minimal pulsation. High-grade 45# round steel and sleeves are meticulously selected to process the entire shaft, securing shaft concentricity and minimizing eccentric shaft forces. This guarantees unparalleled stability in pulley movement. Equipped with high-quality bearings featuring a hot charging mechanism and an innovative bearing block, our inner bearing enlargement device allows seamless bearing positioning, preventing damage from impact. For pulleys enduring forces beyond 80KN, we perform stress elimination treatments, and for belt speeds exceeding 2.5m/s, comprehensive static balance inspections are conducted. We are fully equipped to manufacture an array of pulleys tailored to meet diverse customer specifications, encompassing various types, qualities, and standards.
