Individual track links are a direct bolt-in replacement when chain damage or crack progression is isolated to a section of the assembly. This aftermarket bush-track link 349d is manufactured to OEM pitch, link height, and section dimensions for the 349D — maintains the designed pitch relationship with adjacent links and the drive sprocket.

Why Choose This Bush-Track Link 349D
– Chain pitch and link height: OEM specification for correct sprocket and roller engagement
– Pin bore and seal groove dimensions: confirmed to OEM for press-fit pin assembly
– Link rail surface area: OEM geometry for correct roller contact stress distribution

Heavy-Duty Construction
This bush-track link 349d is manufactured using alloy steel body: carburised and case-hardened rail surfaces for wear resistance. Core toughness retained below the hardened surface to resist fracture from rock impact. Machined rail faces for dimensional accuracy and surface finish. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.
