Engineering Machinery Track Pins (also known as chain pins or connecting pins) serve as the core connecting components in the travel systems of tracked equipment. 

Key Information

Function: Connects track links, acting as the “joints” of the track structure. Withstands tensile forces, impact forces, and torsional forces during equipment movement, ensuring overall track rigidity and transmission stability.

Features: Forged from high-strength alloy steel with carburized and quenched surface treatment, offering high hardness, wear resistance, and fatigue endurance. Smooth ends engage track bushings, while the wear-resistant center section contacts track plates.

Applications: Suitable for tracked equipment like bulldozers and excavators. Common models include Shantui SD22/SD32, Caterpillar D8N, XCMG XE series, etc. Matching track pins must correspond to the specific equipment size.

Track pins are categorized into fixed pins (non-rotating) and floating pins (rotatable). Regular inspection of wear and looseness is crucial for preventing track derailment and extending the service life of the undercarriage system.
