Description

When you’re out in the field and hear that grinding noise coming from a wheel hub or notice play in your bearings, you know you’ve got trouble brewing. A failed bearing doesn’t just make noise—it can seize up and leave you stranded right when you need your equipment most. This Timken 3994 tapered roller bearing cone is built to handle the loads, dirt, and vibration that come with working on farm equipment, keeping your wheels turning smoothly season after season.

What You’re Getting

Precise 2-5/8 inch inner diameter for accurate shaft fit
Tapered roller design that handles both weight and side forces better than straight rollers
Hardened steel construction that resists wear in dusty, demanding conditions
1.183 inch width provides proper load distribution along the shaft
Straight bore design for direct installation on standard shafts

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 tight field corners, this cone keeps things rolling smoothly through planting, cultivating, and harvest seasons.

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.

Installation Notes

This is just the inner cone—you’ll need the matching cup that presses into your hub. 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.
