Description

When your disc gang starts getting noisy or the blades aren’t tracking straight, there’s a good chance it’s time to look at your bearing sleeves. This precision-machined sleeve fits between your disc blades on the gang shaft, maintaining proper spacing so each blade cuts where it should. Without the right sleeve dimensions, your discs will wobble or bunch up, leaving strips of unworked ground that’ll haunt you come planting time.

What You’re Getting

Heavy-duty steel construction built to handle the constant vibration and side loads of field work
Precision 1-3/4 inch outside diameter and 1-1/2 inch inside diameter for snug, wobble-free fit
6-9/16 inch length provides proper blade spacing on 7-1/4 inch gang setups
Works seamlessly with disc spools SMA20621 and SMA20622 for complete gang rebuild

Built for Real Farm Work

This sleeve is designed for John Deere disc harrows that run the 7-1/4 inch blade spacing setup. Whether you’re working corn ground in the spring or chopping stalks after harvest, this sleeve keeps your disc gang running true so every blade does its share of the cutting work.

Made to Last

Farm equipment bearings and sleeves take tremendous abuse from rocks, roots, and the constant pounding of field operations. This sleeve is manufactured from quality steel that resists wear and maintains its dimensions season after season, even in the toughest conditions.

Good to Know

When replacing bearing sleeves, it’s smart to inspect the whole gang while you’ve got it apart. Check for worn spools, damaged blades, and shaft wear that could cause premature failure of your new parts. Pack everything with quality disc bearing grease during assembly – not the general-purpose stuff that’ll wash out in the first muddy field.
