Supplier's note

1. Technical Breakthroughs:

   • Wood Material: 20% lighter than traditional metal bushings, reducing equipment weight while maintaining structural integrity.
   • Cross-Brand Compatibility: Ensures fitment for both Komatsu and Sany machinery, broadening usability.
   • Extended Shelf Life: 1-year durability under storage, outperforming industry-standard 6-month benchmarks.

2. Version Selection Guidance:

   • Base Model: Suitable for standard construction tasks (e.g., light-to-medium load excavators).
   • Advanced Model: Ideal for heavy-duty applications (e.g., loaders in harsh terrains) needing extra reinforcement.
   • Pro Model: Designed for extreme environments (e.g., Arctic mining operations) with ultra-wide temperature tolerance.

With the Pro Model’s -30°C to +80°C range, you can operate reliably in extreme climates. Pair its wood core with Komatsu/Sany compatibility to ensure seamless integration and minimal downtime.
