The idler is used to guide the track to rotate correctly and prevent it from deviating and deviating.
Most excavators also function as rollers. This can increase the contact area of the track to the ground and reduce the ground pressure.
The wheel surface of the guide wheel is made smooth, with the 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 closest roller, the better the guidance.
Material: 40, 50 steel, or 35MN, cast, tempered, hardness HB230-270
In order to make the guide wheel work and extend 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 aligned during installation.
