When your planter starts making that grinding noise or you notice uneven seed depth, chances are your disc opener bearings are crying for help. A bad bearing doesn’t just sound awful—it throws off your whole seeding operation, giving you poor stands and uneven emergence. This Koyo special ag bearing is built specifically for the tough job of cutting through residue and soil, season after season.
What You’re Getting
- Precision-manufactured 5/8 inch round bore fits standard disc opener assemblies
- Special ag construction designed for the constant side loads and debris that come with field work
- Superior sealing keeps dirt and moisture out while keeping grease where it belongs
- Bulk-packed for production efficiency—same quality, smart packaging
- Direct replacement for worn bearings on major planter brands
Built for Real Farm Work
This bearing fits John Deere, Kinze, Case IH, White, and Great Plains planters, including MaxEmerge Plus, Pro, XP, XP Pro, and Case IH 900 and 1200 series units. Whether you’re no-tilling into heavy corn stalks or conventional tilling in clean ground, your disc openers take tremendous abuse cutting through whatever’s in their path and creating the perfect seed trench.
Made to Last
The bearing is designed specifically for disc applications, with superior sealing to keep dirt out and grease in. Farm work means dealing with mud, dust, moisture, and heavy loads that can quickly destroy inferior bearings. This bearing uses quality construction that’s properly heat-treated and manufactured to handle the demanding conditions of agricultural use.
Installation Notes
This is a direct replacement bearing—no modifications needed. Before installing, check your row unit for excessive wear on the opener mounting bracket—a loose fit here will cause premature bearing failure. Pack with quality disc bearing grease during installation, and you’ll be back to cutting clean seed trenches in no time.
