The idler wheel is composed of components such as the wheel body, idler wheel shaft, sleeve, seal ring, and end cap. Idler wheels can be categorized into single-sided and double-sided idler wheels; as well as those used for excavators and bulldozers.
The idler wheel is one type among the four wheels of the undercarriage on crawler-type construction machinery. Its primary function is to support the weight of drilling machines, pavers, crawler cranes, boring machines, excavators, and bulldozers, allowing the tracks to move forward along the wheels. The material for the wheel body is typically 50Mn, 40Mn2, and similar materials, primarily forged and then machined, followed by heat treatment. The hardness of the wheel surface after quenching should reach HRC 45~52 to enhance its surface ***. The machining precision of the idler wheel shaft is quite high, usually requiring CNC machines to achieve the necessary specifications.
Our dual-metal bushes are made from steel sheets sintered with special alloys, offering high load-bearing and fatigue resistance. The floating oil seals, made of special alloys, provide strong sealing performance under harsh conditions such as mud and moisture. Suitable for low-speed, heavy-duty industrial applications. ***.
