Import Cast Iron Ore Mining Cart Wheel Set — Buy in wholesale FOB from Supplier in China

The Cast Iron Ore Mining Cart Wheel Set supplied by Zhongyun Intelligent Machinery (yantai) Co,. Ltd. comprises a range of wheel models designed for heavy‑duty mining carts. Model ZBL600/300 carries a mine car weight of 2400 kg, a track width of 600 mm, a wheel diameter of 300 mm, a maximum axle distance of 808 mm, a minimum cover distance of 510 mm and an axle diameter of 60 mm. Larger variants such as ZBL600/350 increase the weight capacity to 6700 kg and feature a 350 mm wheel diameter with an axle diameter of 80 mm. The biggest configuration, ZBL600/400, supports up to 9000 kg and uses a 400 mm wheel.

All wheels are cast from grey cast iron, a material chosen for its wear resistance and ability to absorb shock in abrasive underground environments. Typical Brinell hardness for this grade lies between 180 and 220 HB, providing a balance of strength and brittleness suitable for ore transport. Standard industry tolerances for wheel diameter are ±2 mm, while axle bore tolerances are ±0.5 mm, ensuring interchangeability across cart frames. The wheels are supplied with a machined flange to accept standard bearing assemblies, a common practice in mining equipment manufacturing.

These wheel sets are primarily purchased by mining equipment integrators and ore‑handling contractors who require robust, low‑maintenance components for underground operations. When sourcing, buyers should confirm the specific model, required quantity, and preferred Incoterm such as FOB Yantai, as the supplier does not publish MOQ or lead time publicly. Payment terms are typically negotiated on a Letter of Credit basis, and buyers are advised to request a material test report confirming hardness and chemical composition before shipment.
