The Carrier Roller, also known as Top Roller or Upper Roller, is installed above the track frame of the Case CX495 crawler excavator.
For a 50-ton class excavator, the undercarriage system operates under extremely high loads during travelling, digging and heavy-duty working conditions. The carrier roller supports the upper track chain, maintains correct chain alignment and helps reduce friction between moving components.
A worn or damaged carrier roller may cause:
Our CX495 carrier rollers are manufactured with professional undercarriage production technology and provide a reliable aftermarket replacement solution for mining contractors, equipment distributors and repair workshops.
