Description

When your disc harrow starts making noise or the gang isn’t spinning smoothly, it’s usually the bearings that are calling it quits. This NTN disc bearing keeps your discs rolling true and your operation running without the headaches of squealing axles or seized gangs. Nothing stops field work faster than bearing failure, and this one’s built to handle the dirt, moisture, and constant rotation that comes with tillage work.

What You’re Getting

Greasable design means you can keep it lubed up for long life—just hit it with the grease gun during regular maintenance
1-1/2 inch square bore fits the most common heavy-duty axle size found on disc harrows and tillage tools
100mm outer diameter provides the load capacity needed for gangs carrying multiple heavy disc blades
Quality NTN construction that meets OEM specs and tolerances
Cylindrical outer race design for proper fit in standard bearing housings

Built for Real Farm Work

This bearing fits disc harrows, vertical tillage tools, and field cultivators that use 1-1/2 inch square axles. Whether you’re running a heavy offset disc through corn stubble or working summer fallow with a field cultivator, this size axle and bearing combo is what manufacturers use when they need something that won’t fold up under load.

Made to Last

Disc bearings take a beating from dirt ingestion, moisture, and constant flexing as the gang follows ground contours. The greasable design lets you push fresh lubricant through to flush out contaminants and keep things running smooth. NTN has been making bearings for decades and knows what it takes to survive in agricultural applications.

Good to Know

This is a direct replacement for most OEM applications using this size. Keep the grease gun handy—regular greasing is what separates bearings that last one season from ones that go the distance. If you’re replacing one bearing in a gang, it’s smart to check the rest while you’re at it.
