Description
When you’re working long hours in the field and start hearing that telltale growl from a wheel hub, you know it’s time to replace those bearings before you’re stuck with a seized wheel. This Timken 18590 tapered roller bearing cone is the inner race assembly that works with its matching cup to keep your tractor wheels, implements, and equipment rolling smoothly through another season.
What You’re Getting
- Precision-engineered cone with 1-5/8 inch inner diameter that fits snugly on your shaft
- Tapered roller design that handles both heavy loads and side forces from turning and uneven terrain
- Quality steel construction with proper heat treatment to resist wear and fatigue
- Genuine Timken engineering built to the same standards as your original equipment
- 0.688-inch width that maintains proper spacing in your bearing assembly
Built for Real Farm Work
This bearing cone is commonly found in wheel hubs on tractors, implements, and transport equipment where you need reliable support for heavy loads. Whether it’s supporting the weight of a loaded grain cart or handling the side loads from turning in muddy fields, these bearings keep things rolling smoothly season after season.
Made to Last
Timken has been making bearings for farm equipment since before your granddad was farming, and they know what it takes to survive in agricultural conditions. The steel is properly hardened to resist wear, and the precision manufacturing means it’ll run true even when things get dusty and dirty out there.
Good to Know
This is just the cone – you’ll need the matching cup to complete your bearing assembly. Always replace bearings in complete sets and use fresh, high-quality wheel bearing grease during installation. Proper torque specifications and bearing adjustment are critical for safe operation and maximum bearing life.
