  • Dual floating oil seal seals bearing chamber, lock internal lubricant to realize long-term automatic lubrication of spindle rotation.
  • Limit upward & lateral displacement of upper track, prevent track sagging, swing and off-track during climbing & rough ground traveling.
  • Disperse instantaneous impact load generated from uneven terrain walking to excavator chassis frame.

Product Competitive Advantages

  • 1:1 original dimension replication, bolt-on direct installation without any on-site modification, save installation labor expense.
  • Deep hardened roller surface plus high-standard floating seal, low failure rate and reduce long-term maintenance replacement cost.
  • Strict full inspection before shipment, extremely low oil leakage rate for qualified finished rollers.
  • Sufficient spot inventory, tiered discount for bulk order, flexible sea/air/express global delivery options.
