Description

When your disc gang isn’t running smooth and you’re hearing more noise than usual from the hub, chances are your bearing sleeve has seen better days. This precision-fit sleeve works alongside your spool to keep everything aligned and spinning freely, so you can get back to breaking ground instead of breaking down in the field.

What You’re Getting

Exact 2-1/8 inch outer diameter and 2 inch inner diameter for proper bearing fit
5-7/8 inch length matches original factory specifications
Works directly with your existing 549977 spool assembly
Precision machined surfaces for smooth bearing operation and long life

Built for Real Farm Work

This sleeve is specifically designed for Case IH disc harrows, particularly the 500, 501, and 596 models that handle everything from field prep to seedbed finishing. These workhorses spend long days breaking up stubble, chopping residue, and smoothing ground, which means their bearings take a real beating.

Made to Last

Farm conditions are tough on bearings, and this sleeve is built to handle the dust, dirt, and constant vibration that comes with disc work. The precise tolerances ensure your bearings seat properly and stay in place, preventing the kind of premature wear that leads to costly downtime during busy seasons.

Good to Know

This sleeve works as part of your complete bearing assembly with the 549977 spool. If you’re rebuilding your disc gang, it’s smart to inspect both pieces together since they work hand-in-hand to keep your bearings running true. Clean everything thoroughly before assembly to get the longest life out of your new parts.
