Description

If you’ve been running disc harrows or other tillage equipment for any length of time, you know that grinding sound when a bearing starts going bad. This NTN disc bearing with its 1-1/2 inch square bore is built to handle the punishment of cutting through corn stubble, turning under crop residue, and prepping seedbeds season after season.

What You’re Getting

Greaseable design lets you maintain it properly instead of throwing it away when it gets dry
100mm outside diameter provides the load capacity needed for heavy disc work
Square bore design eliminates slippage on the axle under heavy loads
Quality NTN construction that’s trusted by equipment manufacturers worldwide
Sealed inner construction keeps dirt and moisture out of the bearing races

Built for Real Farm Work

This bearing fits the disc gangs on harrows, field cultivators, and other tillage tools where you need reliable performance in dirty conditions. Whether you’re running a smaller disc harrow or working with heavier offset discs, this bearing handles the side loads and impact that come with breaking up hard ground and working through trashy fields.

Made to Last

NTN builds these bearings specifically for agricultural applications where they’ll see dirt, moisture, and constant vibration. The greaseable fitting means you can pump fresh grease into it during routine maintenance, extending bearing life far beyond sealed units that can’t be serviced.

Good to Know

When installing, pack the bearing with quality disc bearing grease – not general purpose stuff. The square bore eliminates the need for set screws or other retention methods. If you’re replacing one bearing on a gang, check the others while you’re at it since they typically wear at similar rates.
