D355 IDLER PART NO.:17M-30-00210
Product Overview
Part Number: 17M-30-00210
Fit Machine: Komatsu D355 Heavy Bulldozer
This idler wheel is a heavy-duty aftermarket replacement undercarriage wear part exclusively designed for Komatsu D355 large mining bulldozers. Manufactured from high-strength alloy cast steel with full-rim deep quenching heat treatment, it adjusts track tension and guides track chains to prevent track deviation, slipping and derailment, maintaining stable performance under heavy-load harsh working environments including stone quarries and open-pit mines.
Core Advantages
Precision Machined Replacement Dimensions
Outer diameter, spindle bore and mounting bracket dimensions are precisely machined to fit Komatsu D355 bulldozers perfectly. Direct bolt-on installation is available without cutting or any modification.
Deep Hardened Wheel Rim
Carburizing quenching treatment provides the rim surface with ultra-high wear resistance, greatly extending service life on rocky and muddy mining sites.
Multi-Layer Anti-Mud Sealed Lubrication Structure
Thick composite oil seals block sediment and water ingress while stopping grease leakage, significantly reducing maintenance frequency during mining bulldozer operations.
High Toughness Cast Body
Effectively resists cracking and permanent deformation under long-duration full-load mining pushing work.
Strict Pre-Shipment Quality Inspection
Each idler undergoes hardness testing, hydraulic leak testing and dimensional calibration before packaging to guarantee consistent stable quality.
