Description

When you’re seeing uneven cuts or hearing that grinding noise from your disc gang, chances are you’ve got a bearing that’s given up the fight. This NTN disc bearing with its 1-3/4″ square bore is built to handle the constant pounding and side loads that come with breaking through tough ground and working heavy residue.

What You’re Getting

Greasable design lets you maintain it properly instead of throwing it away when it’s dry
Square bore design prevents slipping on the gang shaft under heavy loads
110mm outer diameter provides solid bearing surface for long service life
2-inch inner ring width distributes loads evenly across the bearing race
Cylindrical outer race fits standard disc bearing housings without modifications

Built for Disc Harrow Work

This bearing fits disc harrows and cultivators with 1-3/4″ square gang shafts. Whether you’re running a tandem disc breaking up corn stalks or a field cultivator working bean stubble, this size bearing is common on mid-size to larger tillage equipment where the gangs need to handle serious loads and keep spinning true.

Made to Last

The bearing itself is designed specifically for disc applications, with superior sealing to keep dirt out and grease in. NTN builds these bearings to handle the constant dirt exposure and shock loads that destroy regular bearings. The square bore prevents the bearing from spinning on worn shafts—a common problem that kills round-bore bearings.

Good to Know

Check your gang shaft for wear before installing the new bearing. A groove worn into the shaft will destroy even a quality bearing in short order. When installing, pack the bearing with quality disc bearing grease, not general purpose. The grease fittings should get attention every 10-15 hours of operation during heavy use.
