Our Factory Manufacturing Strength

We know many ordinary aftermarket idlers are easy to damage in heavy bulldozer working conditions. Most of them adopt thin recycled steel casting, with shallow surface hardening process, which is easy to crack and deform under strong extrusion and impact force.

As a certified factory following ISO 9001 quality management system and CE standard, we completely avoid these quality defects for Idler for Komatsu D155A 175-30-00450. We adopt heavy-duty box-section integral casting design to enhance the overall structural toughness and compression resistance. Meanwhile, we use professional intermediate frequency induction quenching technology only for the rolling surface of 175-30-00450 idler.

The process forms a thick and wear-resistant surface layer, which can resist the abrasion of silica sand and broken stone all year round. The inner part maintains good toughness and ductility, and can buffer strong frontal impact generated in bulldozer operation. All products are inspected layer by layer from forging, machining to heat treatment, and only qualified parts can be delivered from the factory.
