Why Do CAT 320 Track Rollers Matter for Your Excavator Uptime?
Track rollers, or bottom rollers, support the excavator's weight along the track frame, ensuring smooth travel and stability on uneven terrain. Worn rollers lead to undercarriage failure, downtime, and damage to tracks and sprockets, costing Canadian contractors $500–$2,000 per day in lost revenue. AFT Parts rollers maintain uptime for construction and mining operations in Alberta, Ontario, and beyond.
- Absorb shock on rough terrain to prevent track misalignment.
- Critical for heavy-duty use in forestry and mining across BC and Quebec.
