When you’re hearing grinding from a wheel bearing or feeling play in the front wheel, chances are you need this tapered bearing cup. This is the outer race that holds the rollers in place and takes all the side loads from turning, braking, and field work. A worn cup means your bearing’s done for, and replacing just the cone won’t fix the problem.
What You’re Getting
- Precision-ground bearing surface that holds rollers true and handles heavy loads
- 2.875 inch outside diameter with 3/4 inch width for medium-duty applications
- Standard Timken tolerance and quality—same as what came from the factory
- 0.09 inch maximum housing fillet radius for proper fit in most hubs
- Straight outside diameter design that presses in clean and stays put
Built for Real Farm Work
This cup is sized for wheel bearings on a wide range of tractors, implements, and trailers. You’ll find it in front wheel hubs, rear axle housings, and PTO drives where there’s moderate to heavy loading. It works with the matching cone bearing to handle both radial weight and the side forces from turning and working on slopes.
Made to Last
Timken’s been making bearings for over 100 years, and they know what it takes to survive in farm equipment. This cup is made from quality steel that’s heat-treated to handle shock loads and temperature swings. The bearing surface is ground smooth so your rollers run true and last longer.
Installation Notes
This cup presses into the bearing housing—you’ll need a bearing driver or large socket that contacts the outer edge evenly. Check that the housing bore is clean and free of nicks before installation. The cup should go in square and seat fully against the shoulder. Always replace cups and cones as a matched set for best performance.
