Description

When your disc assembly starts making noise or wobbling during operation, it’s time for a new bearing before that failing part damages your expensive gang shaft or causes uneven cutting. This NTN disc bearing keeps your discs running smooth and true, handling the side loads and impacts that come with working through tough field conditions and heavy residue.

What You’re Getting

Greasable design lets you extend bearing life with regular maintenance instead of running until failure
Square bore precisely fits 1-1/4 inch shafts without wobbling or premature wear
Spherical outer race self-aligns to reduce stress on housing and extend service life
Superior sealing keeps dirt out and grease in during demanding field work
OEM-quality construction built specifically for disc bearing applications

Built for Real Farm Work

This bearing is a direct replacement for Case IH part 818112C91 and fits Mathis Triple 7-6 mowers. Whether you’re cutting through corn stalks with your disc harrow or maintaining pastures with your mower, this bearing handles the punishment that comes with agricultural tillage and cutting equipment.

Made to Last

The NTN brand means quality bearings that stand up to farm conditions. The greasable design and specialized sealing system are engineered for the stop-and-go operation typical of tillage work, where bearings face constant direction changes and impact loads that destroy standard bearings.

Good to Know

Pack this bearing with quality disc bearing grease, not general purpose stuff. The greasable fitting makes regular maintenance easy, which extends bearing life significantly. When you’re replacing one bearing, check the others on that same shaft since they typically wear at similar rates—it’ll save you time later.
