The Track Roller, also known as Bottom Roller or Lower Roller, is a key undercarriage component installed beneath the track frame of crawler bulldozers.
The compatible track roller for Komatsu D60 and Shantui SD16 supports the machine operating weight, guides the track chain and helps maintain proper crawler alignment during travelling, grading and earthmoving operations.
During bulldozer operation, track rollers are continuously exposed to:
A worn or damaged track roller may cause:
Our D60 / SD16 track rollers are manufactured using professional undercarriage production processes to provide a reliable aftermarket replacement solution for construction, earthmoving and heavy-duty bulldozer applications.
Designed for compatible:
The same replacement roller can be supplied for both applications where the undercarriage specifications are confirmed to be interchangeable.
Manufactured from:
40Mn2 Alloy Steel
Advantages:
The roller tread surface is induction hardened to improve resistance against abrasive and high-load working conditions.
Suitable for demanding applications involving:
Equipped with:
The sealing system helps prevent lubricant leakage and protects the internal bearing area from:
Manufactured with precision-controlled:
Designed for direct bolt-on installation without modification when the correct configuration is selected.
