Description

When your tractor’s been putting in long hours and you’re hearing that telltale grinding or whining from the wheels, it’s probably time to look at the bearings. This inner bearing cup is the stationary outer race that holds the tapered roller bearings in place – a crucial part that keeps your wheels running smooth and true. When these wear out, you’ll know it from the noise and the wobble.

What You’re Getting

Precision-manufactured cup with 4.125-inch outer diameter that fits perfectly in the hub
Tapered design that works with cone bearings to handle both radial and thrust loads
Durable construction that stands up to the weight and stress of heavy tractor work
Direct replacement that installs just like the original – no modifications needed

Built for Real Farm Work

This bearing cup fits the workhorses of many farms – the 4520, 4620, 4630, 4640, 4840, 5020, and 6030 series tractors. These machines handle everything from field work to loader duty, and their wheel bearings take a beating from heavy loads, rough terrain, and constant use. Whether you’re running a 4630 on the planter or putting a 6030 through harvest season, reliable wheel bearings are what keep you rolling.

Made to Last

The tapered cup and cone design has been the gold standard for heavy-duty applications because it distributes loads evenly and handles both the weight pushing down and the side forces from turning. This cup is built to the same specifications as the original equipment, so you’re getting the durability John Deere designed into these tractors.

Good to Know

Always replace bearing cups and cones as a set – mixing old and new parts leads to premature failure. Make sure the hub is clean and free of any nicks or burrs before pressing in the new cup. A bearing driver or large socket that matches the cup’s outer diameter makes installation much easier than trying to pound it in with a hammer.
