When you hear that growl from a wheel hub or feel play in bearings, it’s time to fix it before you’re stuck with a seized wheel. This Timken 492A bearing cup is the outer race that works with the matching cone to keep your equipment rolling smoothly down country roads and through field work.

Built for Real Farm Work
This bearing cup serves in wheel assemblies across a wide range of agricultural equipment where reliable rotation is critical, from utility tractors for livestock operations to larger row-crop machines pulling heavy implements. These bearings support heavy loads like loaded grain carts and handle side loads from field turns, keeping things rolling smoothly season after season.
Made to Last
Farm equipment faces mud, dust, moisture, and heavy loads that destroy inferior bearings, but this Timken cup uses quality steel construction designed for the demanding conditions of daily farm operations. Tapered roller bearings handle the combination of heavy loads and side forces that comes with farm work.
Installation Notes
This bearing cup works with a matching cone as a complete bearing assembly – always replace bearings in complete sets and use fresh wheel bearing grease during installation. Make sure your hub housing isn’t damaged or worn, and follow your equipment manual’s torque specifications for proper bearing preload and maximum service life.
