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. Tapered roller bearings like this one are workhorses in agricultural equipment because they can handle the combination of heavy loads and side forces that comes with farm work.
Made to Last
Farm equipment faces mud, dust, moisture, and heavy loads that quickly destroy inferior bearings. This is genuine Timken engineering, which means it’s built to the same standards as the bearing that came in your equipment originally. The tapered design distributes loads evenly while the precision manufacturing ensures proper clearances and long service life, even under the demanding conditions of daily farm operations.
Installation Notes
This bearing cup works as part of a complete bearing assembly that includes the matching cone. 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.
