Description

When you hear that grinding noise from your disc harrow or notice the discs starting to wobble, it’s time for new bearings. A worn disc bearing doesn’t just make noise—it throws off your entire tillage pattern and can damage expensive gang shafts if you let it go too long. This NTN disc bearing gets your equipment back to cutting clean furrows and working soil evenly.

Key Features

Greasable design lets you maintain proper lubrication throughout the season
Spherical outer race handles the side loads and impacts that disc gangs take
Premium NTN construction built specifically for agricultural disc applications
90mm outer diameter provides excellent load capacity for heavy soil conditions
Direct replacement bearing—no modifications to your existing gang setup

Built for Real Farm Work

This bearing fits disc harrows and tillage equipment with 1-3/4 inch round gang shafts. Whether you’re working corn ground, breaking up sod, or preparing seedbeds, disc gangs take tremendous abuse from rocks, roots, and heavy residue. This bearing is engineered to handle those harsh conditions that would destroy a standard bearing.

Made to Last

NTN has been building bearings for over a century, and their agricultural line is designed for the punishment that farm equipment dishes out. The spherical outer race compensates for shaft deflection and misalignment that’s common in field conditions, while the greasable design means you can keep fresh lubricant where it’s needed most.

Installation Notes

Mark your gang position before disassembly to maintain proper disc spacing. Clean the shaft thoroughly—old grease mixed with dirt acts like grinding paste. Pack the new bearing with quality disc bearing grease, not general purpose. While you’re in there, check the condition of other bearings on that shaft since they typically wear at similar rates.
