Description
When your ridger or disc harrow starts making that grinding sound that makes you want to cover your ears, chances are you’ve got a failing disc bearing. This 1-1/8 inch square bore bearing is built to handle the tough sideways loads and dirt that come with working the ground, whether you’re building ridges for potatoes or breaking up heavy clay.
What You’re Getting
- Sealed design keeps the dirt out and grease in where it belongs
- Square bore fits precisely on the shaft without slippage or play
- 90mm outer diameter handles heavy radial and thrust loads
- Cylindrical outer race design for straightforward installation
- Quality construction that matches original equipment standards
Built for Real Farm Work
This bearing fits Amco ridgers and various tillage equipment where a 1-1/8 inch square shaft meets a 90mm bearing housing. Whether you’re running an older ridger through sandy soil or working a disc through corn stubble, this bearing handles the punishment that comes with ground-engaging equipment.
Made to Last
Disc bearings take more abuse than just about any other bearing on your equipment. This one’s built with heavy-duty seals and quality steel races to stand up to dirt, moisture, and the constant shock loads that come from hitting rocks and roots. The sealed design means you’re not constantly fighting to keep it greased in dusty conditions.
Good to Know
Before you start the job, mark your disc spacing so everything goes back where it belongs. Clean the shaft thoroughly – any dirt or old grease will act like grinding compound and kill your new bearing fast. A little anti-seize on the shaft threads makes future removal much easier when the time comes.
