Idler for D355 D275 D155A D85EX-12 Excavator Parts front Idler

The wheel body adopts advanced rolling forging technology and box welding structure. Through matrix normalizing and intermediate frequency induction quenching heat treatment, the surface hardness reaches HRC48-54 and the hardening depth is 5-10mm. It has robustness to withstand high impact and abrasion resistance under adverse working conditions.

1.Select a wide of front idler which is suitable for the range from 0.2 to 120 tons of shoes type excavators,bulldozers and special machinery.

2.Sepecial heat treatment process results in longer life,the greatest degree of under heavy load,and prevent fragmentation.

3.Use low and high-double seal makes it life lubrication,it is suitable for standard and specail temperature appication.

4.Choose a broad range of spring reulator,high flexibility and hydrocarbon-type relulator which is applications for mine working condiction
