An updated iteration of KSS Ultimate is in development. Coming Soon.
Track Link Assemblies
Precision-forged track link assemblies featuring SALT — Sealed And Lubricated Track. Engineered for demanding mining cycles on Komatsu and Caterpillar equipment.

Core Technology
SALT — Sealed And Lubricated Track
SALT is KSS's sealed and lubricated track system. Three engineering elements work together to retain lubrication inside the pin-bushing interface for the full service life of the assembly.
Precision-fit seal groups at each pin and bushing pair prevent ground contamination from entering the lubrication chamber. The internal cavity is factory pre-charged with GL5-rated synthetic lubricant — maintaining viscosity stability from −35°C to +50°C and eliminating field re-greasing requirements regardless of operating environment or maintenance intervals.
The base material is boron-alloyed steel, carburized and heat-treated to achieve a hard exterior surface over a tough, impact-resistant core. This dual-property profile resists both surface abrasion and shock loading — the primary failure modes in coal and mineral mining operations.
Engineering Details
Material
Boron steel forging — selected for superior hardenability and toughness under impact loading.
Heat Treatment
Induction hardening to precise case depth specifications. Core toughness maintained to absorb shock loads.
Dimensional Tolerancing
Precision-controlled pitch, height, and bore geometry for accurate interface with sprocket and roller systems.
Pin & Bushing
Carburized bushings with case depth consistently increased in the current specification to extend the hardened wear surface before base material is reached. PPR (Positive Pin Retention) provides a mechanical lock at the pin-link interface — reducing end play and maintaining the seal compression geometry that keeps lubrication in and abrasives out.
Lubrication
Factory pre-charged with GL5-rated synthetic lubricant. The synthetic formulation maintains stable viscosity from −35°C to +50°C — covering cold start conditions and sustained high-temperature cycles in tropical open-cut operations. No field re-greasing required.
Seal Groups
Seal groups are engineered to heavy-duty application standards. Each assembly maintains lubrication chamber integrity across the full service interval — preventing contamination ingress at the pin-bushing interface in abrasive, high-moisture, and laterite soil conditions.
Enhanced Specification
SALT with PPR — For High-Impact Mining Cycles
Sealed and Lubricated Track Chain with PPR is engineered for machines operating in arduous conditions — where high-impact loading and sustained duty cycles accelerate the two most common track chain failure modes: lubrication loss at the pin-link joint, and pin shifting under load.
A hardened metal ring (PPR — Positive Pin Retention) is pressed into the groove between the pin and link, then mechanically deformed into a conical seat. This locks the pin to the link — inhibiting end-play generation and outward link movement on the pin, and maintaining joint sealing even where end-play exceeds the nominal capacity of the seal group.
Key Advantages
- —Track chain specified for fields with high-impact conditions and high-loading mining applications
- —Heavy Duty class track links
- —Significantly increased seal-to-bushing face contact and oil retention
- —Standard pin-and-bushing turn maintenance — no special procedure required
- —Reduced undercarriage maintenance downtime at the fleet level
