Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The E70B idler wheel plays a key role in guiding and tensioning the track chain of your excavator. Positioned at the front of the undercarriage, it supports smooth track movement, maintains proper track tension, and prevents derailment. By reducing shock and wear on the track components, the idler helps prolong the service life of your undercarriage and ensures stable, reliable performance — whether you’re digging, loading, or maneuvering in tough conditions.
Superior Material and Heat Treatment Process
Our E70B idler wheels are manufactured from high-strength alloy steel, carefully selected for its toughness and resistance to heavy loading. The induction hardening process further increases the surface hardness (typically HRC 52-58), allowing it to resist wear, impact, and deformation in challenging terrains.
To provide additional protection against corrosion and abrasives, we apply anti-rust coatings and protective finishes, extending service life and reducing maintenance requirements.
Compatible Models and Serial Numbers
The E70B idler is designed to match:
- Caterpillar E70B excavator
- Other variants in the E Series with similar undercarriage dimensions (such as E60, E80, and E100 models)
Some typical OEM part numbers for this idler include:
- 4I9335
