DAEWOO DH370 fabracted front idler assembly-heavy duty excavator undercarriage parts-supply by DPW parts-a high quality idler manufacture in China.
Product Specifications
Fabricated front idler wheels assembly is a heavy-duty component used in tracked heavy machinery (such as excavators, bulldozers, and crawler cranes) to guide and support the track chain. Unlike cast idlers, which are made from a single poured metal mold, fabricated idlers are constructed by welding and assembling multiple high-strength steel parts.
The DAEWOO DH370 Fabricated Front Idler Wheels Assembly is engineered for mining and construction sites where standard cast idlers fail prematurely. Unlike traditional designs, its modular forged steel construction allows targeted component replacement, saving up to 30% in long-term maintenance costs.
Ultra-Dense Boron Steel Construction
Hot-rolled under precision-controlled conditions for 100% material compactness (no voids or inclusions).
Boron alloy (27MnCrB5/30MnB5) enhances hardness while maintaining weldability.
✅ Defect-Free Manufacturing
Ultrasonic testing (UT) and magnetic particle inspection (MPI) ensure zero cracks or flaws.
Consistent grain structure for uniform stress distribution.
✅ Advanced Heat Treatment
Quenching & tempering achieves HB 400-450 hardness (50% higher than standard rims).
Optimized microstructure resists abrasion in gravel, iron ore, and slag environments.
✅ Engineered for Heavy-Duty Applications
Compatible with loaders, excavators, and dump trucks (e.g., CAT 950, Komatsu WA600).
30% longer lifespan vs. traditional SAE 1045 steel rims.
Key Innovations:
Labyrinth Seal System: Keeps contaminants out even in muddy conditions.
Bolt-On Flange Design: Enables quick tension adjustment without disassembling the track.
ISO 9001-Certified Alloy Steel: 15% higher fatigue resistance than competitors.
