Komatsu PC60-5 Bottom Roller, Waterproof Dustproof Anti-Corrosion Bottom Roller, Leak-Proof Heavy Duty Undercarriage Parts for Southeast Asia Humid & Muddy Construction Sites, OEM Spare Parts In Stock.
Excellent sealing performance, waterproof and mud-proof, adapt to rainy and wet environments.
Anti-rust treatment, effectively resist corrosion in tropical climate.
Standard OEM size, easy installation, perfect match for Komatsu PC60-5.
The Komatsu PC60-5 Bottom Roller is a mining-grade excavator undercarriage component developed for high-load crawler support and reliable operation in extreme working environments. Built with premium alloy steel and advanced sealing technology, this heavy-duty track roller delivers excellent durability, smooth track movement, and long-term wear resistance for demanding excavation applications.
This excavator lower roller is widely used in mining projects, quarry operations, road construction, and heavy earthmoving industries where stable undercarriage performance is critical.
The reinforced roller body is specially designed to withstand continuous heavy-load operation in mining and quarry environments.
Advanced heat treatment improves surface hardness and reduces wear caused by rocks, gravel, and rough terrain.
Supports stable track movement and improves excavator operating efficiency during continuous excavation work.
Floating seal technology effectively prevents oil leakage and protects internal components from mud and dust contamination.
Precision manufacturing and durable material selection help reduce maintenance frequency and extend service life.
The internal structure is engineered to handle high-impact excavation and heavy machine vibration.
The PC60-5 excavator bottom roller is suitable for:
Each Komatsu PC60-5 track roller is manufactured using advanced production processes:
Improves internal density and strengthens load-bearing capacity.
