When you hear that grinding noise coming from your disc gang or notice a blade wobbling instead of cutting clean, chances are you need a new disc bearing. This NTN sealed bearing is built to handle the punishment that comes with working through corn stubble, rocky ground, and heavy residue day after day.
What You’re Getting
- 1-1/8 inch square bore fits perfectly on standard disc harrow shafts
- 80mm outer diameter provides maximum load capacity for heavy tillage work
- Sealed design keeps dirt and moisture out while keeping grease in where it belongs
- Cylindrical outer race design for smooth operation in standard housings
- Heavy-duty construction handles the side loads and impacts of field conditions
Built for Real Farm Work
This bearing replaces John Deere part JD9286 and works on various disc harrows and tillage equipment. Whether you’re running a tandem disc preparing ground for planting or working a heavy offset disc breaking up tough sod, this bearing keeps your gangs spinning true so you get consistent soil preparation across the field.
Made to Last
NTN builds these bearings to OEM specifications using quality steel and proven sealing technology. The sealed design means you don’t have to worry about greasing—it’s pre-packed and ready to work. The square bore gives you a tight fit on the shaft without the slop that leads to premature wear.
Good to Know
This is a direct replacement that slides right onto your existing square axle. While you’ve got the gang apart, check the other bearings on that shaft—they typically wear at similar rates. Pack the bearing housing with quality disc bearing grease during installation for maximum life.
