FRONT IDLER VIO20-2

Production introduction:

The guide wheel is used to guide the track to rotate correctly to prevent its deviation and derailment.            

Most excavators also act as supporting wheels. This can increase the contact area between the track and the ground and reduce the grounding voltage.            

The wheel surface of the guide wheel is made into a smooth surface, and the middle arm ring acts as the guide, while the torus on both sides supports the rail chain.            

The smaller the distance between the guide wheel and the nearest supporting wheel, the better the guidance.         

Material: ZG50MN, casting, tempering, hardness HRC48-HRC56           

Main points:            

In order to make the guide wheel work and prolong its life, the radial runout of the wheel face on the central hole should be less than or equal to 3MM, and the correct alignment should be made when the wheel is installed.
