Core Information

Function: Connects the front and rear ends of the track chain into a closed loop, meshing with the drive sprocket to transmit power while withstanding tensile forces, impact loads, and torsional stresses during equipment movement. It serves as the “locking mechanism” of the track structure.

Features: Forged from high-strength alloy steel with a carburized and quenched surface treatment, offering high hardness, wear resistance, and fatigue strength; Available in detachable (with pin/spring clip) and fixed (welded) types; detachable models facilitate track installation and maintenance.

Applications: Compatible with tracked equipment like bulldozers and excavators, commonly used in Shantui SD22/SD32 models. Matching chain links with corresponding pitch is required for different equipment.

The installation precision of chain links directly impacts track running stability. During installation, ensure the clearance between pins and chain links meets specifications to prevent track misalignment or abnormal noise caused by excessive gaps. Routine maintenance requires regular inspection of chain link wear and locking status. Replace immediately when wear exceeds limits or locking fails to prevent track breakage and potential safety incidents.
