Product Description
Manufactured as OEM equivalent aftermarket accessory, the CAT E200B track roller, also named CAT E200B bottom roller or E200B excavator support roller, ranks as core CAT E200B undercarriage part of CAT E200B crawler excavator chassis system, widely known as heavy-duty E200B carrier roller / CAT E200B chassis roller for whole machine weight bearing and track guiding. Made of high-strength 40Mn2 manganese alloy steel via precision forging & integral surface quenching, this load-bearing roller bears full vehicle dead weight, restricts lateral track deviation and smooths traveling movement during digging, loading and rough terrain transfer. Strictly copied per original CAT blueprint dimension & mounting hole layout, it is direct replacement for original worn, leaking and broken rollers, top stocked spare part for global excavator repair shops, construction fleet owners and undercarriage spare parts bulk distributors.
