Description
Precision Manufacturing Process
Every D7G idler is produced under strict quality standards to ensure reliable field performance.
Production begins with carefully selected raw materials, followed by casting or forging of the wheel body. Precision CNC machining is then performed on critical dimensions and mounting surfaces to ensure accurate fitment. Heat treatment enhances durability, while final assembly and inspection verify operational reliability before shipment
Idler Bearing Machining & Assembly
The central bearing of the idler is manufactured using high-strength 50Mn steel, providing excellent load-bearing capacity and resistance to impact. Precision machining and strict assembly control ensure smooth rotation and long-term durability for Caterpillar D6D and D6H bulldozers.
Idler Surface Heat Treatment Process
The idler shell undergoes advanced heat treatment to improve surface hardness and structural strength. This process enhances wear resistance and protects the component from deformation under heavy load and harsh working conditions.
Anti-Corrosion Coating & Painting
After machining and heat treatment, the idler is treated with anti-corrosion coating and finished with industrial-grade painting. This protective layer helps prevent rust and extends the service life during operation, storage, and transportation.
Final Inspection & Warehouse Preparation
Each idler is thoroughly inspected before being stored and prepared for shipment. With organized warehouse management and secure packaging, the products are delivered in optimal condition, ready for installation in D6 series bulldozers.
