The idler wheel is one type of four wheels attached to the undercarriage of crawler-type engineering machinery. Its primary function is to support the weight of drilling machines, pavers, crawler cranes, trenchers, excavators, and bulldozers, allowing the tracks to move forward along the wheels. The wheel body material is typically 50Mn, 40Mn2, and similar materials, mainly forged and then mechanically processed, followed by heat treatment. The hardness of the wheel surface after quenching should reach HRC 45~52. The machining precision of the idler wheel shaft is quite high, usually requiring CNC machine tools to meet the requirements.
