Description
When you’re rebuilding disc gang bearings or ripper bearings on your John Deere tillage equipment, these nylon liners are the precision components that keep everything running smooth and tight. They’re designed to work with the main bearing housing and handle the constant rotation and dirt that comes with field work. You need two of these liners per bearing assembly, and they’re built to give you years of reliable service.
Key Features
- Precision-molded nylon construction that handles the stress of heavy tillage work
- Direct replacement for worn liners – no modifications needed
- Works specifically with SMA241911 bearing assemblies for proper fit and function
- Two required per bearing assembly for complete rebuild
- Engineered to resist wear from dirt and debris that gets into disc gang areas
Built for Real Farm Work
These liners fit John Deere disc harrows and rippers that see heavy use in tough field conditions. The 2620, 2623, and 2625 disc harrows are popular mid-size machines used for breaking up crop residue and preparing seedbeds, while the 2720 and 2730 rippers handle the tough job of breaking through compacted soil layers. All these implements put serious stress on their bearing assemblies.
Made to Last
Nylon was chosen for these liners because it handles the combination of rotational wear and contamination better than metal alternatives. The material resists galling and binding while providing smooth operation even when dirt works its way into the bearing area. These aren’t just generic plastic parts – they’re engineered specifically for the demanding conditions of tillage equipment.
Installation Notes
You’ll need to completely disassemble the bearing housing to replace these liners, so plan on doing both at the same time along with checking the main bearing. Clean all components thoroughly before reassembly – any dirt or debris will cause premature wear. The liners should fit snugly but not require excessive force to install.
