Description
When you’ve got machinery that needs to keep rolling smoothly through the harvest season, the last thing you want is a bearing failure that leaves you stuck in the field. This Timken tapered roller bearing cup is built to handle the heavy loads and constant vibration that come with farm work, whether it’s in your tractor’s wheel hub, implement attachment points, or other rotating machinery.
What You’re Getting
- Precision-ground steel construction that stands up to heavy loads and field abuse
- Standard tolerance design ensures proper fit with matching cone bearings
- 4.25-inch outside diameter with 0.875-inch width for specific applications
- 0.030-inch maximum housing fillet radius accommodates most standard housings
Built for Real Farm Work
This bearing cup is commonly found in wheel hubs, PTO assemblies, and implement drives across various tractor and equipment brands. The tapered design distributes both radial and thrust loads evenly, making it perfect for applications where machinery takes a beating from rough fields and heavy implements.
Made to Last
Timken’s been making bearings for over a century, and they know what it takes to survive in agricultural conditions. This cup is manufactured from hardened steel and precision-ground to exact tolerances, so it’ll keep your equipment running smoothly season after season.
Installation Notes
This is the outer cup that presses into your housing—you’ll need the matching tapered cone to complete the bearing assembly. Make sure your housing bore is clean and properly sized before installation. A bearing driver or press makes installation much easier than trying to hammer it in.
