Description
When your disc gang starts making that grinding noise or wobbling through the field, you know it’s time for new bearings. A failed trunnion bearing doesn’t just mean rough operation—it can lead to uneven tillage, shaft damage, and costly downtime right when field conditions are perfect for working ground.
What You’re Getting
- Complete housing and bearing assembly saves you the hassle of sourcing individual components
- 1-3/4 inch round bore fits standard Sunflower and Landoll disc gang shafts perfectly
- Heavy-duty construction handles the side loads and impacts that come with cutting through tough residue and varying soil conditions
- Sealed bearing design keeps dirt and moisture out while keeping critical grease where it belongs
- Direct replacement for SN3090—no modifications or adapters needed
Built for Real Farm Work
This assembly is designed for Sunflower and Landoll disc harrows—the workhorses that break up compaction, incorporate crop residue, and prep your seedbed season after season. Whether you’re working corn stalks in the fall or getting ground ready for spring planting, these machines take a beating, and this bearing assembly is built to handle it.
Made to Last
Your disc harrow works in some of the toughest conditions on the farm, and this trunnion bearing assembly is built to match that durability. The castings are designed to distribute loads properly, while the bearing itself features superior sealing to keep contaminants out and extend service life even when working through dusty or muddy conditions.
Installation Notes
You’ll need to remove the entire gang shaft to access the bearing, so mark your disc positions before disassembly to maintain proper spacing. Clean everything thoroughly—old grease mixed with dirt acts like grinding paste. Pack the new bearing with quality disc bearing grease, not general purpose stuff, and check that shaft for wear since a grooved axle will quickly destroy your new bearing.
