Caterpillar 80HSP-00 High-Strength Roller Chain
The 80HSP-00 is a heavy-duty, high-strength roller chain purpose-built for Caterpillar equipment operating in the most demanding environments — including open-pit mining, underground extraction, heavy construction, and continuous manufacturing lines. It is engineered to sustain over 10 million fatigue cycles without failure, making it a benchmark product in the ANSI #80H series for reliability and service life.
Every component is manufactured from alloyed steel selected specifically for its combination of tensile strength, impact resistance, and wear characteristics. The result is a chain that maintains dimensional accuracy and performance consistency throughout its full service life — even under shock loading, abrasive dust, and extreme-temperature conditions typical of Caterpillar machine cycles.

Component Materials & Part Numbers
| Inga. | Part Number | Component | Material | Unit Weight (g) |
|---|---|---|---|---|
| 1 | 80HXP-F1-00-01 | Outer Chain Plate | 40 miljoner | 25.1 |
| 2 | 80HSP-00-02-MA | Stift | 42CrMo | 13.8 |
| 3 | 80HSP-00-03 | Inner Chain Plate | 40 miljoner | 26.1 |
| 4 | 80H-00-04 | Seamless Sleeve (Bushing) | 20CrMo | 8.9 |
| 5 | 80-00-05-MA | Roller | 35CrMo | 11.1 |
Material note: 40Mn plates deliver high fatigue strength at the link joints. 42CrMo pins provide superior shear resistance under shock loading. The 20CrMo seamless bushing is carburized and hardened to resist internal wear, while the 35CrMo roller resists surface fatigue against sprocket teeth.
Key Engineering Features
- ✓
10+ million fatigue cycle rating — verified through pulsator testing to ANSI B29.1 protocols; performance remains consistent post-test with no measurable elongation beyond tolerance. - ✓
Seamless bushing construction — the cold-drawn seamless sleeve eliminates the weld seam that is a common failure initiation point in standard kedjor, extending hinge life significantly. - ✓
Shot-peened plates — the outer and inner plates are shot-peened after heat treatment to induce compressive residual stress at the plate surface, resisting crack initiation under cyclic bending loads. - ✓
Pre-loaded assembly — chains are pre-stressed during assembly to stabilize initial elongation, allowing more predictable replacement intervals and tighter tolerance fit on Caterpillar sprockets. - ✓
Corrosion resistance — all components are phosphate-treated and oil-coated at final inspection, providing immediate protection during storage and initial service before re-lubrication. - ✓
Direct Caterpillar fitment — dimensional interchangeability verified against OEM sprocket tooth profiles for Caterpillar machines using #80H chain drives; no modification required.
Typical Applications
The 80HSP-00 is used wherever a Caterpillar machine’s chain drive is expected to operate continuously under high tensile load or cyclic shock, including:
Mining
Dragline drives, underground haulage, continuous miner chain assemblies, coal preparation plant conveyors
Construction
Trencher chain drives, paver conveyors, crawler crane undercarriage drive chains, compactor drives
Heavy Manufacturing
Steel plant overhead handling, foundry conveyor drives, press transfer lines, forge shop equipment
Forestry & Quarrying
Timber harvester feed chains, felling head drives, quarry crusher feeder drives, screen deck drives
Installation & Maintenance Guidelines
Correct maintenance is the single largest factor in achieving the full rated life of the 80HSP-00. Follow these guidelines:
- 1
Initial lubrication check: Inspect the factory-applied lubricant before installation. If the chain has been in storage for more than 12 months or shows dried lubricant, flush and re-lubricate with a chain-specific oil (ISO VG 100–150) before running. - 2
Correct initial tension: Set sag to 2–3% of the span length for drive applications. Over-tensioning is a leading cause of premature plate fatigue. - 3
Lubrication interval: In normal operating conditions, lubricate every 250 operating hours. In dusty or wet environments (quarrying, mining), reduce to every 125 hours. Use drip or bath lubrication where possible; avoid dry-running at all times. - 4
Elongation check: Replace the chain when measured pitch elongation exceeds 2% (≥ 25.9 mm average pitch over a 10-link span). Do not allow elongation to reach 3%, as sprocket tooth damage will follow rapidly. - 5
Sprocket inspection: When replacing the chain, always inspect the mating sprocket for hooked tooth wear. A worn sprocket will accelerate elongation of a new chain. Replace sprockets showing tooth face wear beyond 10% of original tooth width.
Matching Sprockets
We supply precision-machined sprockets for the 80HSP-00 chain in standard tooth counts (9T to 45T) with bored-to-size or taper-lock bore options. Sprockets are manufactured from C45 steel (hardened tooth flanks) or cast iron for light-duty applications. Contact us with your tooth count, bore diameter, and shaft configuration for a prompt quotation.
