Description

When you’re working disc harrows, cultivators, or other tillage equipment, you know how critical disc bearings are for keeping your gangs spinning smooth. When dirt, moisture, and constant field vibration start taking their toll, this sealed disc bearing gives you the reliability you need to keep planting, tilling, and prepping fields without the downtime. This 7/8″ square bore bearing is built specifically for the smaller tillage implements that run these lighter axle sizes.

What You’re Getting

87mm outer diameter design that provides the bearing capacity needed for field work
Sealed construction that protects internal components from dirt and water infiltration
1.438 inch inner ring width and 1.188 inch outer ring width for proper load distribution
Spherical outer race shape that allows for shaft misalignment common in field conditions
Pre-lubricated and sealed for long service life without regular maintenance

Built for Real Farm Work

This bearing is designed for disc harrows, field cultivators, and other tillage implements where the square axle setup is standard. Whether you’re working behind a utility tractor breaking up compacted soil or pulling a heavy disc across uneven ground, this bearing handles the side loads and impacts that come with field work. It’s particularly well-suited for smaller cultivators and disc harrows that use 7/8″ square axles.

Made to Last

The sealed design protects the internal components from dirt and water infiltration, while the quality steel construction stands up to the shock loads and vibration that would kill a standard bearing. Timken’s precision manufacturing ensures smooth rotation even under the demanding conditions of tillage work where constant impacts and debris are part of the job.

Installation Notes

This is a direct replacement for worn bearings—no modifications needed. When installing, make sure the axle is clean and free of burrs. A light coating of anti-seize on the axle helps with future removal, and always check that retaining hardware is properly torqued to spec.
