💡 Why do tracked machines lose drive tension and alignment fast?
Worn bearings create drag that speeds up undercarriage fatigue on rugged sites.
- Handy sealed roller assemblies cut friction and shut out road grit
- Straight tube shaft setups keep tracks centered when grinding around curves
- Regular swap replacements bring back factory pitch ratios for smoother hauling
