Origin Machinery is a dedicated manufacturer of crawler undercarriage components with more than ten years of field-proven expertise, operating an integrated production base of 230,000 m² with three specialized plants and an annual capacity exceeding 100,000 undercarriage sets. We supply the D275 front idler wheel — also known as guide wheel or track idler — as a direct OEM replacement for Komatsu D275-series bulldozers. Positioned at the front of the track frame, the idler maintains correct track tension and guides the track chain, directly influencing undercarriage stability and service life under continuous heavy load. Each unit ships with the matched shaft and mounting collar for straightforward on-site fitment.


Origin Machinery runs an intelligent manufacturing system across forging, CNC machining, heat treatment, assembly and coating. More than 40 flexible production lines — including German five-station automatic hot-forging, heat-treatment and friction-welding lines — are coordinated through MES, PDM, SAP and SCADA for real-time process control and full traceability. A complete in-house laboratory performs raw-material spectroscopy, metallographic analysis, hardness and three-coordinate measurement, plus crawler fatigue and floating-seal endurance testing, so every lot is verified before it leaves the plant.

The D275 front idler is engineered for Komatsu D275 bulldozers working in demanding sectors:

All D275 idlers are produced under our ISO 9001 quality management system, supported by ISO 14001, ISO 45001 and ISO 50001 certification. With 100+ granted patents and three provincial-level R&D centers, we maintain documented raw-material certification, in-process control and final testing per unit, providing complete traceability and responsive after-sales support.
