Cat® HDXL with DuraLink™

Innovation drives 20 to 40% longer life

Designed for maximum durability, this patented system consists of Cat® heavy duty extended life (HDXL) with DuraLink, larger diameter bushing, track roller, and sprocket segments. This combination creates a link assembly with more wear material and improved life. It handles your most demanding terrain without breaking. Enhancements include:

D6-D7

• Improved link to help eliminate cracking and spalling
• PPR2 provides better pin retention for longer life sealability
• Larger bolt improves shoe retention in severe applications

D8-D11

• New crowned link helps to eliminate link scalloping
  
• Increased bushing material for extended wear life
• Improved sealing system eliminates dry joint issues

 

Move more material, more efficiently
