The Track Roller — also known as Bottom Roller or Lower Roller — is a key undercarriage component installed beneath the track frame of Case CX80 crawler excavators.
The roller carries the machine operating weight, supports the track chain and ensures smooth movement of the crawler system. During excavation, landscaping and construction operations, track rollers are exposed to continuous loading, vibration, mud and abrasive materials.
A worn track roller may lead to:
Our Case CX80 track rollers are manufactured according to OEM-style dimensions, providing a reliable aftermarket replacement solution for construction and earthmoving applications.
