Description
When you start hearing noise from a wheel hub or notice play in your tractor’s wheels, it’s time to address those bearings before they leave you stuck in the field. This Timken 14123A tapered roller bearing cone is the inner part of your bearing assembly—the piece that rides on the shaft and handles both weight and side loads that come with hard farm work.
What You’re Getting
- Precision-engineered Timken quality built to handle heavy loads and tough conditions
- 1-1/4 inch straight bore that fits your shaft perfectly with no play or binding
- 26.721mm width provides proper load distribution across the bearing race
- Steel construction with proper heat treatment to resist wear and fatigue
- Standard tolerance manufacturing for reliable fit with your existing bearing cup
Built for Real Farm Work
This bearing cone is designed for agricultural equipment where rotating shafts carry heavy loads and face side forces from turning, loading, and uneven terrain. You’ll find this type of bearing in wheel hubs, transmission assemblies, and implement drives where smooth operation and long life matter most.
Made to Last
Timken has been making bearings for over a century, and this cone shows that experience. The steel is properly heat-treated to handle the stress cycles of farm work, while the precision manufacturing ensures it’ll run smooth and quiet when properly greased and adjusted.
Good to Know
Remember, this is just the cone—you’ll need the matching cup that presses into your hub housing. Always replace tapered bearings in complete sets and pack them with high-quality bearing grease before installation. Proper torque and adjustment are critical for safe operation and maximum bearing life.
