When you’re dealing with noise or vibration coming from your tractor’s differential or transmission, there’s a good chance worn bearings are the culprit. When you’re in the middle of planting or harvest and a bearing starts howling, you’ve got bigger problems than just the noise. This Timken 30308M tapered roller bearing cone is designed to handle the heavy loads and constant rotation that come with powering through your workday.

40mm bore diameter with precision tolerances for smooth shaft operation
Properly hardened steel construction that resists wear and runs true even when things get dusty and dirty
Built to handle both radial and thrust loads without breaking a sweat, making them workhorses in agricultural equipment
23mm width provides solid support for high-stress applications

Built for Real Farm Work

This bearing cone is the kind of precision-made component that keeps your machinery running smoothly, whether it’s in a tractor transmission, implement drive system, or other heavy-duty application. You’ll find similar bearings in everything from tractor transmissions and final drives to implement gearboxes and PTO assemblies where precise shaft positioning and smooth operation matter.

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. This bearing uses quality steel construction with proper heat treatment to handle the demanding conditions of agricultural use. The precise manufacturing tolerances ensure smooth operation and long service life when properly maintained with quality grease.

Installation Notes

This bearing cone works as part of a complete bearing assembly that includes the matching cup. Always replace bearings in complete sets and use fresh, high-quality bearing grease during installation. Make sure shaft surfaces are clean and check for any scoring that could cause premature wear.
