or frequent breakdowns, it’s time for a transformative upgrade. Our

1. What is a Idler?
The "Tension Core" of Excavator Undercarriages Spare Parts
As a critical component of the track tensioning system, the idler
assembly maintains proper track sag, guides track alignment, and
absorbs impacts during operation. Our forged tension roller
features a splined shaft-roller connection and heavy-duty steel construction, designed specifically for
Hitachi EX55 Excavator. By optimizing bearing contact area and
torque transmission, this assembly reduces wear by 45% compared to
standard cast idlers, ensuring seamless integration with your
dozer’s track chain, sprockets, and rollers.
2.1 Forged for the Toughest Conditions
Our track idlers are forged from high-strength alloy steel using
advanced precision hot-forging techniques, delivering exceptional
durability. Built to withstand extreme loads and impacts, they
excel in harsh construction and mining environments—reliable even
on rugged terrain or dense soil.
2.2 Precision Engineering for Optimal Functionality
Meticulously designed with optimized structure, our tension wheels
ensure steady track alignment. This reduces friction and wear,
extending undercarriage component lifespan by 40% vs. conventional
models. The result: fewer replacements, lower maintenance costs,
and boosted job site productivity.
