Hitachi Construction Machinery Mini Undercarriage Component Parts EX60-2 Track Carrier Rollers
What is a Roller?
The track roller supports the conveyor belt and material weight, accounting for 35% of total conveyor cost and generating over 70% of resistance, making roller quality critically important.
Available in materials 40Mn2, 40MnB, or 50Mn depending on working conditions. Precision forged and heat-treated to achieve surface hardness of HRC52-6 with hardened layer depth of 7-10mm (HRC45) for durability, impact resistance, and wear resistance.
High-quality floating seals and lubrication system adapt to temperatures from -45℃ to 120℃, requiring no maintenance under severe conditions.
Carrier Rollers Features
Quench-tempering processes ensure excellent mechanical properties, high strength, and superior wear resistance.
Surface hardness HRC40-55 reduces wear and extends service life.
Precision engineering, careful heat-treatment, and lifetime sealing system guarantee long operational life.
Forged deep hardening steel shells resist bell mouthing, with all rollers carrying warranty.
