Description
When that middle tension arm roller on your John Deere round baler starts making noise or gets notchy, it’s the bearing telling you it’s time for a replacement. That hex bore bearing takes a beating from all the constant rotation and the load of keeping your bale chamber tight. This NTN bearing is designed specifically for JD round balers and fits the middle tension arm roller perfectly.

Built for Real Farm Work
This bearing handles the demanding job of supporting the middle tension arm roller in your round baler’s chamber. Whether you’re baling first cutting hay, straw after harvest, or making silage bales, that roller needs to rotate smoothly under constant pressure. The tension system depends on this bearing to maintain proper belt tracking and chamber geometry as your baler forms consistent, tight bales.
Made to Last
The sealed design protects the bearing internals from the dust, moisture, and debris that round balers face daily. NTN uses quality steel and precision manufacturing to create bearings that handle the shock loads and vibration of field conditions. The hex bore eliminates the need for separate locking collars or set screws that can work loose.
Good to Know
Installation is straightforward – remove the old bearing and press the new one into place. The hex bore slides right onto the hex shaft for a secure, no-slip fit. Keep some bearing grease handy for the mounting surfaces, and check that the roller spins freely after installation. If you’re replacing one bearing, it’s often smart to do both sides while you’ve got things apart.
