According to the power, the crawler bulldozer has 4 to 7 rollers on each side, and the lower limit of the power is lower. The guide wheel is used to guide the track to revolve correctly and prevent it from deviating and deviating. Most excavators also play the role of supporting wheels.

The wheel surface of the guide wheel is made into a smooth surface, with a baffle arm ring in the middle as a guide, and the ring surfaces on both sides support the rail chain.
The smaller the distance between the guide wheel and the nearest support wheel, the better the guidance. Material: 40, 50 steel, or 35MN, casting, quenching and tempering treatment, hardness HB230-270 Key points: In order to make the guide wheel work and extend its life, the radial runout of the center hole of the wheel face should be less than or equal to 3MM, install It must be correctly aligned.
