This 20Y-30-00013 PC200 lower track roller is a heavy-duty load-bearing roller tailored for PC200 series excavator heavy-duty track supporting systems. Different from ordinary overall quenching or shallow quenching track rollers on the market, this bottom roller adopts professional medium frequency surface quenching technology. This targeted heat treatment realizes layered hardness distribution: high-hardness outer roller surface for anti-wear performance, and tough inner roller body for anti-impact capacity. It perfectly fits long-term heavy load support, frequent vibration and uneven ground construction scenarios, delivering balanced wear resistance and structural toughness for heavy-duty track operation.

Most common track rollers adopt full integral quenching or shallow quenching process. Full quenching makes roller body overly hard and easy to crack under heavy impact; shallow quenching leads to thin hardened layer and fast surface wear after short service time. Our 20Y-30-00013 track roller applies accurate medium frequency quenching with controllable heating depth and uniform heating speed. Each finished roller will be tested for hardened layer depth and surface hardness one by one. This layered heat treatment solves the industry point that single quenching cannot balance wear resistance and impact resistance for heavy-duty track supporting systems.
This medium frequency quenching lower roller is specially designed for PC200 excavator heavy-duty track supporting system replacement and harsh site undercarriage maintenance. All products get professional anti-rust treatment, waterproof film wrapping and shockproof wooden box packaging to prevent transportation damage. We provide quenching process inspection reports, sample testing and bulk wholesale service, supplying professionally heat-treated heavy-duty chassis parts for global engineering equipment wholesalers and repair factories.
