Bulldozer undercarriage parts D41 front idler track idler roller 

  Idlers are used to guide the track around correctly and prevent it from mistracking and deviating. The idlers of most hydraulic excavators also play the role of rollers, which can increase the contact area of the track to the ground and reduce the specific pressure of grounding. The wheel face of the idler is made smooth, with shoulder rings in the middle for guidance, and the rings on both sides to support the rail chain. The smaller the distance between the idler and the nearest roller, the better the guidance. The idler is usually cast and quenched and tempered with 40, 45 steel or 35Mn steel, and the hardness is HB230~270
