Heavy Duty Extended Pitch Idler

These sprocket idlers are designed for extended pitch chain. These Aetna idlers are manufactured with heavier gauge steel for greater life and load carrying capacity. They are installed with standard 1/2″ or 5/8″ bolts, and include accurately contoured hardened teeth to resist wear and damage to the chain. Aetna idlers are compact and easy to install and built for a long maintenance-free service life. Typical applications include gathering chains on corn heads and other harvesting equipment.
