Our Komatsu PC360 Interchangeable Series Buckets are designed to meet the rigorous production and reliability standards of 35-ton class heavy-duty hydraulic excavators. Fully optimized for the Komatsu PC360-7, PC360-8, and PC360-8M0 platforms, these buckets are available in varying capacities—from 1.6 m³ for heavy rock mining to 1.9 m³ for high-volume earthmoving. Every bucket is precision-engineered to withstand maximum breakout forces, delivering accelerated cycle times and extended service life in high-impact environments such as quarries, open-pit mining, and heavy infrastructure projects.
Optimized Capacity & Geometry: Formulated to maximize the powerful hydraulic profile of the PC360. The dual-radius design optimizes material rollback, speeding up bucket filling and minimizing fuel consumption.
Premium Hardox/NM Structural Alloy: Critical high-friction and high-impact areas—including the lip cutting edge, side cutting blades, and bottom heel runners—are built from NM400 / NM500 or Hardox wear-resistant steel.
Perfect OEM Adapter Alignment: Pre-fitted with standard Komatsu-style 207-939-5120 two-strap adapters and matching side-pin teeth, ensuring zero-play fitment and complete structural interchangeability.
Reinforced Box Section Ear Plates: Thickened upper linkage plates distribute severe prying forces evenly through the bucket chassis, preventing structural distortion and wing cracking.

Mass Civil Infrastructure: Deep mainline trenching, foundational mass excavation, and high-volume truck loading.
Quarry & Aggregates: Loading fractured limestone, basalt, shot-rock, and abrasive river gravel run-offs.
Open-Pit Mining Operations: Stripping heavy compacted overburden and handling dense mineral extraction layers.
Double-Strap Bottom Runners: Thick horizontal wear plates shield the underbelly of the bucket shell from abrasion tracking during drag-back cycles.
Chocky Bar & Button Protection: Rock variants feature high-chromium white iron wear blocks protecting the high-stress corner welds from thinning.
CNC Machined Pin Bushings: Ear plates are precision line-bored for an exact fit with Komatsu bucket pins, preventing structural twisting and seal scoring.
