Idler has important technical functions because these parts must support strongly all tracks without any waving or unbalance and also must help the track drive smoothly.
Idler covers sufficiently these main points not only with the strong body made by the best steel casting and the heat treatment but with the perfect guarantee against the oil-leakage with the good quality of Seal groups. Moreover, the hardness, HRC 50-65, of the round girth of Idler has so high that a long life can be possible.
Apart from casting idler, the forging idler is also available for some excavators which has higher quality than the casting idler.
Suitable for machines of Caterpillar, Komatsu, Hitachi, Volvo, Hyundai, Doosan, JCB, Case, Kobelco, Liebherr, John Deere and so on.
