Product Overview

The Carrier Roller, also known as Top Roller or Upper Roller, is mounted above the track frame of the Volvo EC460 crawler excavator.

For a 46-ton class excavator, the undercarriage system operates under extremely high loads during digging, travelling and continuous heavy-duty operation. The carrier roller supports the upper track chain, maintains correct track alignment and reduces friction between moving undercarriage components.

A worn or damaged carrier roller may cause:

Excessive track chain vibration
Abnormal travelling noise
Increased track resistance
Uneven chain movement
Accelerated wear of track links and bushings
Increased maintenance costs

Our EC460 carrier rollers are manufactured using professional undercarriage production processes and provide a reliable aftermarket replacement solution for equipment dealers, mining contractors and repair workshops.
