Description
When your tractor starts making grinding noises from the wheels or you notice play in the hub, it’s time to replace those worn bearings before you’re stuck with a seized wheel in the middle of harvest. This Timken 3420 tapered roller bearing cup provides the precision fit and durability you need to keep your wheels rolling smoothly, whether you’re navigating tight field turns or hauling heavy loads down country roads. The cup works as the outer race that presses into your hub, forming half of the bearing assembly that keeps everything spinning true.
What You’re Getting
- Quality steel construction with proper heat treatment to handle demanding farm conditions
- 3.125 inch outer diameter with 0.9375 inch width for precise fit in your hub
- Tapered design that distributes loads evenly while handling both radial and thrust forces
- Timken engineering that’s been proven in agricultural conditions for generations
Built for Real Farm Work
This bearing cup serves in wheel assemblies across a wide range of agricultural equipment where reliable rotation is critical for safe operation, from smaller utility tractors for livestock operations to larger row-crop machines pulling heavy implements. Tapered roller bearings like this one are workhorses in agricultural equipment because they can handle the combination of heavy loads and side forces that comes with farm work.
Made to Last
Farm equipment faces mud, dust, moisture, and heavy loads that quickly destroy inferior bearings. The precision manufacturing means it’ll run true even when things get dusty and dirty. This is genuine Timken quality built to the same standards as original equipment.
Installation Notes
This is just the outer cup—you’ll need the matching cone that rides on your axle to complete the bearing assembly. Make sure to pack the bearing properly with grease before installation, and check that your hub races aren’t worn or pitted. A little extra time on the bearing service will save you a breakdown later when you can’t afford the downtime.
