Bogie Parts fits CATERPILLAR D8 D9 D10 KOMATSU D275 D375 D475

1. Bogie Minor
Function: The "Bogie Minor" typically refers to a compact bogie assembly or sub-unit used in lighter-duty rail or industrial transport systems.

Application: Light-duty rail carts, underground mining vehicles, and factory shuttles.

Features:

Modular and compact design for easy integration;

Customizable wheelbase and wheel size;

Material: High-strength structural steel or heat-treated alloy steel;

Surface Treatment: Shot blasting, e-coating, or powder coating for anti-corrosion.

2. Bogie Pin
Function: A critical pin that connects the bogie to the vehicle frame, allowing controlled rotational motion and load transfer.

Performance Requirements:

High wear resistance;

Precision fit for rotational stability;

Material: 40Cr, 42CrMo alloy steel with quenching and tempering;

Machining Tolerance: ISO H7/h6, surface finish ≤ Ra0.8 µm;

Heat Treatment: Induction hardening or carburizing available.

3. Cap Idler
Function: Protects and seals the end of the idler wheel, preventing dust and contaminants from entering the bearing housing.

Structure:

Forged or cast as a single unit;

Designed with sealing grooves for O-rings or oil seals;

Application: Tracked undercarriages, mining locomotives;

Material: Ductile iron, cast steel, or reinforced polymers;

Sealing Options: Nitrile or fluororubber oil seals, optional grease fittings.

4. Cap Roller
Function: Covers the roller end, ensures grease retention, and protects against debris.

Design:

Typically bolted or snap-fitted;

Grease nipple or lube port optional;

Material: Medium-carbon steel, engineering plastics, or alloyed steel;

Surface Treatment: Phosphating, powder coating, or galvanization.

5. Guide
Function: Ensures lateral alignment of the bogie within the vehicle system, stabilizing movement and reducing derailment risk.

Types:

Side guide blocks;

Slide bush guides;

Material Options:

Bronze or copper-alloy (self-lubricating type);

PTFE composites;

Heat-treated carbon steel;

Mounting: Welded or bolted depending on configuration.

6. Plate
Function: Structural reinforcement between the bogie and chassis, helping distribute load and absorb stress.

Types:

Reinforcement Plates;

Mounting Base Plates;

Design Considerations:

Optimized thickness and rib patterns;

Precision-drilled bolt holes for accurate installation;

Material: Q235, Q345B, or wear-resistant steel (NM400/NM500);

Finishing: Hot-dip galvanizing or industrial paint systems.
