Greasable Disc Bearing with Spherical Outer Race

Description

When you’re running a disc harrow through tough field conditions, the last thing you want is a bearing failure that leaves you stuck in the middle of tillage season. This NTN disc bearing is built to handle the side loads, dirt, and impacts that come with cutting through corn stalks and working stubble. The square bore design keeps things secure on your axle while the spherical outer race lets the bearing self-align even when your shaft isn’t perfectly straight.

What You’re Getting

• Greasable design lets you maintain the bearing with fresh grease during busy seasons
• Square bore provides a secure, non-slip fit on square axles without keyways
• Spherical outer race reduces stress from shaft misalignment and extends bearing life
• Heavy-duty construction designed specifically for the harsh conditions of disc tillage
• 85mm outer diameter provides the strength needed for agricultural applications

Built for Real Farm Work

This bearing fits disc harrows, cultivators, and other tillage equipment that use 1-1/4 inch square axles. Whether you’re breaking up ground after harvest or preparing seedbeds in the spring, this bearing handles the constant vibration and side loads that destroy regular bearings. It’s designed for the stop-and-go operation and heavy impacts typical of field work.

Made to Last

NTN builds their disc bearings to agricultural standards, not automotive ones. The bearing races are hardened to handle dirt contamination and the grease fittings are positioned where you can actually reach them for maintenance. The spherical design compensates for the shaft flex and housing wear that’s common in older tillage equipment.

Good to Know

The greasable design means you can pump fresh grease into the bearing during the season to flush out dirt and keep things running smooth. Use quality disc bearing grease, not general purpose – it’s formulated for the loads and conditions these bearings see. Check your axle for wear where the bearing rides; a grooved shaft will destroy even the best bearing quickly.
