Description

If you’ve ever dealt with a wobbly disc or that grinding sound coming from your disc harrow, you know how important a good bearing is to keep things running smooth. This NTN disc bearing handles the heavy loads and constant spinning that comes with cutting through corn stalks, working residue, and preparing seedbeds. When your discs aren’t tracking straight or you’re feeling excessive vibration, it’s usually time for new bearings.

What You’re Getting

Sealed design keeps dirt, debris, and moisture out while holding the grease in where it belongs
Spherical outer race allows the bearing to self-align, handling the side loads that come with field work
Heavy-duty construction built to handle the shock loads from rocks, roots, and uneven terrain
Precision manufacturing ensures smooth operation and long service life even in dusty conditions

Built for Real Farm Work

This bearing is commonly used on disc harrows, vertical tillage tools, and other ground-engaging equipment where discs spin on axles. Whether you’re working a Krause disc harrow, Case IH tillage tool, or other brand of field cultivator, this bearing handles the constant rotation and side loads that come with breaking up compacted soil and incorporating crop residue.

Made to Last

NTN has been making bearings for decades, and this one’s built to farm standards. The sealed design means you won’t be out there with a grease gun every few hours, and the materials can handle the temperature swings and vibration that come with field work. It’s the kind of part that keeps working when cheaper bearings would already be toast.

Installation Notes

This is a direct replacement for most disc applications with the same bore size. Make sure to clean out the bearing housing before installing the new bearing, and check that the axle isn’t worn or bent. A little anti-seize on the outer race makes future removal easier when it’s time for the next rebuild.
