Factory Price SK60-8 Lug-Pattern Excavator Track Roller Bottom Roller for 6-Ton Kobelco SK60-8-Series

The SK60-8 track roller is ​​exclusively designed for the SK60-8 mini excavator​​ from Kobelco. It is tailored to fit the machine’s unique undercarriage dimensions, including track pitch, roller diameter, and bore size. Using a non-compatible track roller (e.g., from other SK-series models or brands) can lead to poor track engagement, increased vibration, and accelerated wear on the track chain and other undercarriage components.

Our production involves rigorous quality-controlled processes:

• High-grade Material Selection: Components are crafted from premium materials for maximum durability
• Outer Race/Shell: High-carbon chromium bearing steel (SUJ2) for superior hardness and wear resistance
• Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
• Seals & Lubrication: Nitrile rubber (NBR) seals for oil resistance with lithium-based grease for long-term lubrication
• Quality Assurance: All materials undergo thorough inspection for chemical composition and mechanical properties using spectrometers and hardness testers
