There’s nothing quite like the sound of a disc harrow working properly—that steady rhythm as each disc blade cuts cleanly through soil and residue. But when disc bearings start wearing out, you’ll hear grinding, feel vibration in the machine, and notice uneven cut quality. This sealed disc bearing keeps your discs running smooth and true, so you can focus on creating the perfect seedbed instead of worrying about bearing failures.
What You’re Getting
- 1-1/2 inch square bore fits standard disc gang shafts on most makes
- 100mm spherical outer race self-aligns to handle field conditions and shaft flex
- Factory sealed design means no grease fittings to maintain—just install and forget
- Heavy-duty construction handles the constant impact and loading of tillage work
- Direct replacement for original equipment on multiple brands and models
Built for Real Farm Work
This bearing works on disc harrows from brands like Amco, Athens, Massey Ferguson, and International Harvester that use square gang shafts. Whether you’re running a tandem disc for primary tillage, finishing discs for seedbed prep, or a heavy offset disc breaking up tough ground, these bearings handle the punishment. The spherical outer race design lets the bearing adjust to shaft deflection that’s common when you’re working through varying soil conditions or heavy residue.
Made to Last
Farm equipment bearings take tremendous abuse from dirt, moisture, impact loads, and constant vibration. The sealed design keeps lubricant where it belongs and contaminants out, so you don’t have to worry about daily greasing or premature failure from dirt infiltration. Quality materials and precision manufacturing mean this bearing will outlast cheaper alternatives that fail when you need them most.
Installation Notes
This is a direct bolt-in replacement for worn bearings. Clean the gang shaft thoroughly before installation and check that it’s not worn or bent. While you’ve got the bearing off, inspect the disc blade mounting and spacers for wear. A few minutes of preventive maintenance now saves hours of downtime during planting season.
