The Track Roller, also known as Bottom Roller or Lower Roller, is an important undercarriage component installed beneath the track frame of Sumitomo crawler excavators.
The compatible roller for SH55, SH60 and SH80 supports the machine operating weight, guides the track chain and helps maintain correct crawler alignment during travelling and excavation.
Track rollers operate in demanding conditions involving:
A worn or damaged track roller may cause:
Our Sumitomo SH55/SH60/SH80 track rollers are manufactured using professional undercarriage production processes to provide a reliable aftermarket replacement solution for equipment dealers, repair workshops and machine owners.
Designed for compatible:
Public aftermarket catalogues also group SH55, SH60, SH75 and SH80 under the same Track Roller product, supporting the use of a common product listing where the actual dimensions are confirmed.
Manufactured from:
40Mn2 Alloy Steel
Advantages:
The roller tread surface is induction hardened to improve resistance against abrasive working conditions.
Suitable for applications involving:
公开同类 SH55/SH60/SH80 产品资料也采用约 HRC48-54、4-10mm 的参数，因此你们自己的实际生产标准如果是 HRC52-58 / 5-10mm，可以继续使用你们公司的标准参数。
Equipped with:
The sealing system helps prevent lubricant leakage and protects the internal bearing area from dust, mud and water contamination.
Manufactured with precision-controlled:
Designed for direct bolt-on replacement without modification when the correct configuration is selected.
