Heavy-duty idler sprocket for cornhead gathering chains. Sealed bearing & hardened steel.
Detailed
The Importance of Replacing Sprocket
Harvest windows are short, and downtime is expensive. This Lower Idler Sprocket Unit is engineered specifically for the brutal environment of corn harvesting. Located at the bottom of the row unit, this component takes the brunt of the dirt and load.
Standard replacement idlers often fail when dust penetrates cheap bearing seals, causing them to seize up and snap your gathering chains. Our units are built differently. We utilize industrial-grade, multi-seal bearings encased in a hardened steel sprocket body. Whether you are running in dry dust or wet, muddy conditions, this idler ensures consistent chain tension and reliable crop intake into the auger.
Swap it out quickly before the season starts and harvest with confidence.

FAQs
Does This Come With The Bearing Installed?
Yes, this is a complete "unit" or "assembly." The heavy-duty sealed bearing is already pressed into the sprocket hub. It is ready to bolt on.
Do I need to grease this sprocket?
No. It uses a sealed-for-life bearing pre-packed with high-quality grease designed to last through normal harvest seasons without maintenance.
How do I know if my current idler needs replacing?
Check for excessive side-to-side wobble, rough or gritty rotation when spun by hand, or significant wear/hooking on the sprocket teeth profiles.
