Bogie Pin for Bulldozer Undercarriage

Short Description:

The bulldozer bogie pin is a critical component in the undercarriage system of tracked heavy equipment. It connects the carrier (or bogie) roller to the track frame, ensuring stable movement under extreme loads and harsh working conditions. Engineered for maximum durability and wear resistance, our bogie pins are designed to extend the service life of bulldozers operating in demanding environments such as mining, forestry, construction, and earthmoving.

Bogie Pin Features

1.High-Strength Alloy Steel Construction
Manufactured from premium materials such as 40Cr, 42CrMo, or customized grades for superior load-bearing capacity.

2.Advanced Surface Hardening Treatments
Induction hardening or carburizing applied to critical areas to enhance surface hardness (HRC 50–58), ensuring excellent wear resistance and fatigue strength.

3.Precision Machining
CNC machining ensures tight tolerances, excellent concentricity, and seamless fit with mating components, minimizing vibration and premature wear.

4.Corrosion Protection
Surface treatments such as black oxide, zinc plating, or phosphate coating are available to resist corrosion in humid, abrasive, or chemical environments.
