The Komatsu D155 Bulldozer Track Link Assembly is a key component of the crawler undercarriage, supporting the track shoes, rollers, sprocket, and idler during heavy-duty dozing and earthmoving operations. Xiamen Doozer supplies replacement track link assemblies for Komatsu D155-series bulldozers, providing a reliable solution for worn or damaged undercarriage components.

Komatsu D155-series bulldozers use sealed and lubricated track systems designed to protect the pin and bushing area from abrasive materials. On the D155AX-8, Komatsu specifies a lubricated track system with sealed components, while the machine uses 42 track shoes per side in its standard configuration.

High Strength Track Links
The track link assembly is designed to withstand repeated loads generated during heavy dozing, traveling, turning, and operation on demanding ground conditions.

Durable Pin and Bushing Interface
The track link works together with track pins and bushings to form the crawler chain. Proper fit between these components helps maintain track alignment and reduce abnormal wear.

Designed for Heavy-Duty Undercarriage Systems
Komatsu maintenance information for the D155AX-6 specifies a basic link pitch of approximately 228.85 mm, providing a useful reference when inspecting or replacing the track chain.

Replacement for Worn Track Chains
A complete track link assembly can provide a practical replacement solution when the existing links, pins, or bushings have reached their service limits.

Multiple D155 Configurations
Track chain specifications can vary between D155A, D155AX and different serial-number ranges. Xiamen Doozer recommends confirming the exact machine model and serial number before quotation.
