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. Whether you’re working with smaller utility tractors for livestock operations or larger row-crop machines pulling heavy implements, proper wheel bearings are essential for maintaining control and preventing costly breakdowns during busy seasons. It’s commonly found in wheel hubs on tractors, implements, and transport equipment where you need reliable support for heavy loads, handling both the weight of loaded equipment and the side loads from turning in the field.

Made to Last

Farm equipment faces mud, dust, moisture, and heavy loads that quickly destroy inferior bearings. 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

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. Make sure to pack the bearing properly with grease before installation, and check that your hub races aren’t worn or pitted.
