Heavy-Duty Replacement Front Idler for Your Kobelco SK70SR
Keep your track running straight and properly tensioned with a precision-engineered replacement front idler for the Kobelco SK70SR excavator. The front idler guides the track at the front of the undercarriage and works with the track tensioner to maintain correct tension, preventing slack, uneven wear, and de-tracking. Built from heat-treated, high-strength steel for long service life — at the best value in the business.
Why the Front Idler Matters
Engineered for Guidance & Tension
The front idler on your Kobelco SK70SR sits at the front of the track frame and is a key part of the tensioning system. As the track adjuster is greased, the idler moves forward to take up slack, keeping the track tight on the undercarriage. A worn, seized, or damaged idler leads to track slap, accelerated track and roller wear, and de-tracking.
Our replacement idlers are manufactured from high-strength cast/forged steel, heat-treated for surface hardness and core toughness, and built with sealed, durable bearings to keep out dirt and moisture for reliable performance in demanding conditions.

Front Idlers & Your Undercarriage System
The front idler guides the track and maintains tension at the front of the undercarriage.
Keep Your Undercarriage Healthy
Undercarriage components account for over half of a machine’s lifetime maintenance cost. Inspect your front idler regularly for wear on the running surface, flange damage, and bearing play. Prompt replacement of a failing idler prevents more expensive damage to your tracks, rollers, and sprocket.
