D155 bulldozer undercarriage parts track idler roller front idler assy
Product Description
D155 idler wheel is used to guide the crawler to rotate correctly and prevent it from deviating and deviating from the track. Most excavators also function as rollers. This can increase the contact area of the track to the ground and reduce the ground specific pressure. The wheel surface of the guide wheel is made of smooth surface, and there is a retaining arm ring in the middle as a guiding function, and the ring surfaces on both sides support the rail chain.
The main points of the excavator idler:
In order to make the excavator D155 idler work and prolong its life, the radial runout of the wheel facing the center hole should be less than or equal to 3MM, and it should be correctly centered during installation.
The excavator d155 idler adopts the box structure cast by resin sand process. The appearance quality of the wheel body has reasonable mechanical structure performance. The matrix is normalized to obtain good impact resistance, and the medium frequency induction quenching heat treatment of the track surface. Surface hardness To hrc48-54, the depth is not less than 6mm, with wear resistance in harsh conditions
