Description

When your disc harrow bearings start grinding or your stalk devastator isn’t rolling smooth, you know it’s time for replacement bearings. A worn disc bearing doesn’t just make noise—it creates uneven cutting, tears up stalks instead of shredding them properly, and can leave you with poor residue management that hurts next year’s planting. This sealed disc bearing gets your equipment back to working like it should.

What You’re Getting

1-1/4 inch square bore fits your existing gang shaft perfectly
85mm outer diameter with spherical outer race handles side loads from cutting action
Factory sealed design keeps dirt and debris out while holding grease in
Pre-lubricated and ready to install—no messy greasing required
Heavy-duty construction built specifically for disc applications

Built for Real Farm Work

This bearing fits Massey Ferguson 520 and 620 disc harrows and Yetter Stalk Devastator equipment, machines that see some of the toughest conditions in agriculture. Whether you’re working through corn stalks, cutting up cover crops, or preparing ground for planting, these bearings handle the constant impacts and side loads that come with aggressive tillage work.

Made to Last

Disc bearings take tremendous abuse from rocks, debris, and the constant pounding of field work. This sealed bearing keeps contamination out and lubricant in, which is critical when you’re working in dusty conditions or muddy fields. The spherical outer race design lets the bearing self-align under load, reducing stress points that cause premature failure.

Installation Notes

This is a direct replacement bearing—slides right onto your square gang shaft without modifications. When installing, clean the shaft thoroughly and check for wear grooves that might damage the new bearing. A light coat of anti-seize on the shaft makes future removal much easier when it’s replacement time again.
