Why Lubricated (SALT) Track Chain?
Up to 50% Longer Life vs. Sealed Chain: The oil-lubricated SALT design vacuum-fills the space between pin and bushing with oil after pressing, dramatically reducing metal-to-metal friction. Compared to conventional sealed chains, SALT track links extend service life by more than 50% . That translates to fewer changeouts, less downtime, and lower cost per operating hour.
- Superior Wear Resistance: Minimal contact between pin and bush decreases premature wear, while premium Korean seals prevent soil and debris infiltration — keeping grease in and contaminants out .
- Weather & Corrosion Resistant: Synthetic grease and advanced sealing technology resist weather influences and corrosion, ensuring consistent performance in harsh working environments .
- Enhanced Mobility & Speed: The oil-lubricated design (SALT chain) provides increased mobility and speed of tracking compared to greased chains — ideal for dozers that work long shifts under heavy load .
- Extended Lifespan: Greased/sealed designs alone extend chain life by over 20% compared to standard chains, while our full SALT oil-lubricated configuration pushes that benefit past 50% .
- Optimized Undercarriage Performance: The track chain guides the track in and out of the track rollers, intermittently supports the machine’s weight, and controls slack and tension — all critical functions for stable D6D operation .
Why Choose Our D6D Track Link?

- Forged 35MnB Boron Steel: Our track links are forged (not cast) from high-strength 35MnB boron steel, then quench-tempered to deliver HRC 51–58 surface hardness with an 8–12 mm deep hardened layer .
- Premium Korean Seals & Oil Recycling: Equipped with a good lubricated oil recycle system and high-quality Korean seals to maximize durability and deliver up to 4,000 hours of warranty coverage .
- Factory-Direct Pricing: Source straight from our production line — genuine-level OEM quality at a competitive aftermarket price, no dealer markup.
- Complete Undercarriage Solution: We also supply track rollers, carrier rollers, front idlers, sprockets, track shoes, cutting edges, and recoil spring assemblies for the D6D and the entire Caterpillar D-series dozer range . One-stop sourcing for your whole undercarriage.
- Rigorous Quality Control: Every track link is forged, quenched, and tempered with deep-hardened rails averaging HRC 53 surface hardness . ISO 9001:2000 certified manufacturing ensures consistent quality batch after batch.
Applications:
Designed for Caterpillar D6D dozers operating in construction, road building, mining, quarrying, landfill operations, site preparation, and heavy earthmoving. Whether you’re pushing overburden, building haul roads, or stripping topsoil, our lubricated track link keeps your D6D productive through every shift.
Fitment Note:
Chain Length Matters: The D6D track chain is available in different link counts — including 36L (for D6D and CAT 955L) and 39L configurations. Common OEM references include 117-1018 / 3P1118 (36L) and 6Y4267 / 6Y4274 (39L) . Before ordering, please confirm:
- Your D6D machine serial number prefix (e.g., 19B-, 1Y-, 5X-, 30X-, 74W-, 9FK-, DD 3X-, PS 20X-)
- Required chain length (number of links)
- Track shoe width and grouser type
