Riveted Flange Disc Bearing for Case IH 500 and 770 Series Disc Harrows

Description

When you’re breaking ground with your Case IH disc harrow and start hearing that telltale grinding or wobbling in the disc gang, it’s time for new bearings. A worn disc bearing doesn’t just make noise—it creates uneven tillage, puts stress on the entire gang assembly, and can leave you with a broken shaft right when you need to be in the field. This riveted flange disc bearing puts everything back to smooth operation.

What You’re Getting

• 2-3/16 inch round bore with precision fit for proper disc alignment
• Riveted flange construction handles the side loads and impacts of heavy tillage work
• Greasable design lets you maintain the bearing for maximum service life
• 5-1/2 inch bolt circle matches original factory specifications
• Direct replacement—no modifications needed to get back to work

Built for Real Farm Work

This bearing is designed specifically for Case IH 500 and 770 series disc harrows—machines built to handle tough residue, rocky soils, and the demanding conditions of modern farming. Whether you’re working corn stubble in the fall or preparing seedbeds in spring, these disc harrows see serious use, and the bearings need to keep up with that workload.

Made to Last

The riveted flange design isn’t just about convenience—it’s about durability. This construction distributes loads across the entire flange face, reducing stress concentrations that cause premature failure. The greasable fitting means you can keep fresh lubricant flowing to the bearing races, extending service life even in dusty, demanding conditions.

Installation Notes

This is a bolt-in replacement that uses the same mounting pattern as your original bearing. Before installation, clean the gang shaft thoroughly and check for wear—a grooved shaft will quickly destroy your new bearing. Pack the bearing with quality disc bearing grease, not general purpose, for best results.
