Description
When you’re out there working residue and your disc harrow starts making that grinding noise that makes you cringe, it’s time for a new bearing. This NTN disc bearing is built to handle the constant loads and dirt exposure that come with tillage work, keeping your discs spinning smoothly instead of wobbling through the field.
What You’re Getting
- 1-1/4 inch square bore fits common small disc harrow axles perfectly
- 85mm outer diameter and spherical outer race handles side loads from disc operation
- Sealed construction keeps dirt and debris out while holding grease in
- NTN quality means reliable performance through tough field conditions
- Precise 1.438 inch inner ring width ensures proper shaft fit
Built for Real Farm Work
This bearing works on various disc harrows and tillage equipment that use 1-1/4 inch square axles. You’ll find this size on utility discs, smaller tandem disc harrows, and some vertical tillage equipment. These machines typically handle lighter tillage duties like seedbed prep, residue management, and working in food plots or smaller acreage.
Made to Last
NTN builds these bearings specifically for agricultural applications where dirt, moisture, and constant vibration are facts of life. The sealed design protects the internal components while the spherical outer race accommodates the slight misalignment that happens when discs encounter rocks, roots, and uneven ground.
Installation Notes
This is a direct replacement bearing – no modifications needed. Clean the axle thoroughly and check for wear grooves that could damage your new bearing. Pack with quality disc bearing grease, not general purpose stuff. A good tip from the field: replace bearings in pairs or sets since they typically wear at similar rates.
