Industry studies put undercarriage at 40–50% of a tracked machine's lifetime repair and maintenance cost. On Saudi terrain — abrasive silica sand, sharp limestone, long travel distances between cut and fill — the wear rates sit at the harsh end of global averages. That makes undercarriage buying a financial decision first and a parts decision second.
The Only Metric That Matters: SAR Per Hour
A track chain at SAR 18,000 that delivers 4,000 hours costs SAR 4.50/hour. A "bargain" chain at SAR 11,000 that stretches out at 1,800 hours costs SAR 6.11/hour — plus an extra installation, plus the sprocket it ruined by accelerating wear. Always divide price by realistic service life, and always include the components a premature failure takes with it.
Match Components or Waste Money
Undercarriage parts wear as a system. A new chain on a hooked, worn sprocket wears to match the sprocket within weeks — you paid for new and got old. The standing rules:
