Description
When your Miller disc starts making that grinding noise or you feel wobble in the disc gang, it’s time to address those worn bearings before they damage your axle shaft. This complete bearing and housing assembly gives you everything you need for a proper repair – not just a bearing that’ll fail again next season, but a complete solution that’ll keep your disc cutting through residue like it should.
What You’re Getting
- Quality Timken GW211PPB2 bearing built specifically for disc harrow loads
- Heavy-duty AgSmart 4-bolt housing that won’t crack under field stress
- Greasable design lets you maintain the bearing for longer life
- 2-3/16 inch inner diameter fits Miller disc gang axles properly
- Pre-drilled 4-bolt mounting pattern for quick, secure installation
Built for Real Farm Work
Miller disc harrows are workhorses that cut through heavy residue and tough soil conditions. This bearing assembly is designed to handle those side loads and impacts that come from cutting through corn stalks, incorporating crop residue, and working in rocky ground. The housing design distributes stress properly so you won’t be dealing with cracked castings mid-season.
Made to Last
The Timken bearing inside this housing is engineered for agricultural disc applications, with seals that keep dirt and debris out while holding grease in. The AgSmart housing is built heavy enough to handle the punishment of field work without the brittleness you sometimes see in cheaper housings that crack at the bolt holes.
Good to Know
This is a direct bolt-in replacement using standard 1/2 inch bolts. When you’re replacing one bearing, it’s smart to check the others on that gang shaft – they usually wear at similar rates. Pack the bearing with quality disc bearing grease during installation, and make sure those grease fittings are accessible for regular maintenance. Having a spare on hand during tillage season can save you from downtime when field conditions are perfect.
