Product Description

Bulldozer D6H D6T D6R D7G D7H D7R for bulldozer track parts

Our final drive sprockets and segments are core undercarriage components that drive the crawler track, efficiently transmitting the driving force from the final drive motor through a precise gear structure. We provide two main specialized solutions:

  • Sprocket Rims (Integral Drive Gear): Designed for mini and medium excavators. These one-piece integrated wheels feature CNC precision machining to ensure a perfect match with track chains, offering easy installation, stable power transfer, and reduced track wear.
  • Sprocket Segments (Gear Teeth): Specifically designed for heavy-duty bulldozers and large mining excavators. The thickened, detachable split-tooth block design handles extreme, high-load conditions. It allows operators to replace only the worn single segments instead of the entire rim, drastically cutting down maintenance costs and machine downtime.


Detachable Split Tooth Block Dozer Sprocket Segment

Features

  • Premium Materials
    Forged and cast from high-quality wear-resistant alloy steel (50Mn / 40MnB / 42MnB).
  • Advanced Heat Treatment
    Utilizes quench-tempering processes and full tooth induction hardening to guarantee superior mechanical properties.
  • Deep Hardened Surface
    Achieves a high surface hardness of HRC 50-58 with a hardened depth of 8mm-12mm.
  • Precision Engineering
    CNC precision machining ensures strict adherence to OEM installment sizes for direct replacement without any modification.
  • Protective Finish
    Treated with shot blasting and anti-rust coating, featuring a smooth finish painted in industrial black or yellow.

  • Functions

    • Compatible Equipment: Ideal for excavators, bulldozers, and crawler backhoes (e.g., Doosan DX225LCA, DX340LC). Fitting major brands including CAT, Komatsu, Hitachi, Volvo, Doosan, JCB, Shantui, Kobelco, and Hyundai.
    • Industry Scenarios: Widely applied in earthmoving, road construction, stone quarries, open-pit mining, and mountain rock pushing.
    • Working Environments: Engineered to excel in harsh, high-load rock and mining conditions.


    Advantages

    • Exceptional Durability: Deep hardened wear surfaces provide high strength and superior resistance to bending, breakage, and strong impacts.
    • Cost-Effective Maintenance: The split-segment design means you only replace what is broken, saving significant time and replacement costs.
    • Strict Quality Assurance: Manufactured under precise design and strict quality control. ISO9001:2008 certified and backed by a One-Year Quality Guarantee.
    • Customization & Supply: Factory wholesale direct supply with flexible options to produce exactly as per clients' samples, designs, and drawings, including custom sizes and logos. Fast delivery within 10-20 days after advance payment.
