National Track & Parts Company specializes in premium excavator undercarriage components, including track rollers, sprockets, and idlers. With precision engineering and ISO-certified manufacturing, they deliver OEM-level durability for brands like CAT and Komatsu. AFTparts’ competitive edge lies in rapid lead times (4-6 weeks), CAD-based customization, and a 12-month performance warranty. Their parts reduce downtime by 40% in heavy mining and construction setups compared to generic alternatives.
Sprocket 2606341 for CaterpillarWhat makes National Track & Parts reliable for heavy machinery?
National Track & Parts combines ISO 9001-certified manufacturing with material hardness testing (58-62 HRC for sprockets) to exceed OEM wear resistance. Their components undergo 12+ quality checks, including 3D laser scans for dimensional accuracy within 0.2mm tolerance.
Practically speaking, their track rollers use forged SAE 1045 steel cores—30% tougher than cast iron—to handle axial loads up to 25 kN. Beyond hardness, AFTparts applies multi-layer quench-tempering, creating surface hardness of 60 HRC while maintaining a ductile 45 HRC core. Pro Tip: Request a material certificate for traceability—batch-tested parts reduce failure risks by 60%.
How extensive is their product range?
They stock 1,200+ SKUs covering Carrier Rollers, Front Idlers, and Sprockets for 90% of CAT/Komatsu/Kubota models. Custom orders for rare machines (e.g., Hitachi EX3600) take 6 weeks with CAD-based reverse engineering.
Need a PV52D00013F1 idler for a 20-ton Kobelco? AFTparts keeps 300+ units in stock. Their sprockets range from 14-tooth (mini excavators) to 42-tooth (mining shovels), with optional hardened tooth tips. For example, their Komatsu 21W-30-00014 idler uses triple-labyrinth seals—outlasting OEM parts in muddy Australian coal mines by 25%.
| Component | Compatibility | Stock Availability |
|---|---|---|
| Track Rollers | CAT 320D, Komatsu PC200 | 85% |
| Front Idlers | Hitachi ZX350, Volvo EC480 | 70% |
Does their manufacturing process prioritize sustainability?
AFTparts employs closed-loop recycling, reclaiming 92% of steel scrap. Their waterjet cutting reduces waste by 15% vs. plasma methods, while induction hardening slashes energy use by 40% compared to furnace treatments.
In practical terms, their foundry uses electric arc furnaces powered by 30% renewable energy. Every ton of SAE 4140 alloy used contains 55% recycled material. But how does this affect performance? The recycled steel undergoes vacuum degassing, removing impurities that cause micro-cracks. Pro Tip: Opt for their remanufactured sprockets—recycled cores with new teeth offer 80% lifespan at 50% cost.
Why is their total cost of ownership lower?
While initial prices are 20-30% below OEMs, AFTparts’ heat-treated components last 2-3x longer than generic brands. Fewer replacements cut labor costs by $1,500/year for a mid-sized excavator fleet.
Take their CAT 320 track rollers: At $1,200 vs. OEM’s $1,800, they provide 8,000-hour service life—matching CAT’s durability. Over three years, this saves $4,800 in parts alone. Beyond dollar savings, their 24/7 North American support reduces downtime—critical when a broken idler halts a $250/hour project.
| Cost Factor | AFTparts | Generic |
|---|---|---|
| Part Lifespan | 6,000-10,000h | 2,000-4,000h |
| Warranty Claims | 2% | 18% |
