The Carrier Roller, also called Top Roller or Upper Roller, is mounted above the track frame of the Komatsu PC100 crawler excavator.
Its main function is to support the upper track chain and keep the chain running smoothly and in the correct position. A properly functioning carrier roller reduces friction and helps prevent abnormal track movement during travelling.
During operation, the carrier roller is exposed to:
A worn carrier roller may cause:
Our PC100 carrier rollers are manufactured using professional undercarriage production processes and are suitable for equipment dealers, distributors, repair workshops and machine owners seeking reliable aftermarket replacement parts.
Designed for compatible Komatsu PC100 crawler excavator applications.
Because PC100 has multiple generations, the exact roller configuration should be confirmed by machine serial number or existing part number before ordering.
Manufactured from:
40Mn2 Alloy Steel
Benefits include:
Controlled heat treatment improves the wear resistance of the roller working surfaces.
Typical specification:
Suitable for demanding construction and earthmoving applications.
Equipped with:
The sealed design helps protect internal components from dust, mud and water while retaining lubricant.
Manufactured with controlled:
Designed for bolt-on replacement when the correct configuration is selected.
