When your disc harrow starts making that grinding noise or the discs aren’t cutting cleanly anymore, chances are good you’ve got a bearing going bad. This 1-inch square bore disc bearing is designed specifically for disc applications, with superior sealing to keep dirt out and grease in, while side rings maintain proper spacing and protect the bearing from debris intrusion. It’s the same reliable replacement that gets your tillage equipment back to working like it should.
What You’re Getting
- Sealed bearing construction keeps contaminants out during tough field conditions
- Spherical outer race design allows for shaft misalignment that’s common in field work
- 1-inch square bore fits snugly on your disc gang shaft without wobbling
- 80mm outside diameter provides the load capacity needed for heavy tillage work
- Direct replacement for multiple OEM part numbers across Case and Massey Ferguson equipment
Built for Real Farm Work
This bearing fits a wide range of utility disc harrows from manufacturers like Case, Massey Ferguson, Amco, Burch, International Harvester, Krause, Tufline, and White. Whether you’re breaking up corn stubble, incorporating cover crops, or preparing a clean seedbed, this bearing handles the constant jarring and side loads that come with disc work.
Made to Last
The bearing itself is designed specifically for disc applications, with superior sealing to keep dirt out and grease in. Excessively worn or bent blades put extra stress on bearings, so this one’s built with the robust construction needed to handle those demanding conditions season after season.
Installation Notes
Replacing a disc bearing is manageable with basic tools – you’ll need to remove the entire gang shaft to access the failed bearing, and clean everything thoroughly since old grease mixed with dirt is like grinding paste. Check the shaft for wear where the bearing rides; a grooved shaft will quickly destroy your new bearing. While you have the gang apart, inspect all bearings on that shaft since they typically wear at similar rates.
