The TIMKEN tapered roller cup is the outer race of a tapered roller bearing assembly. It works together with a cone, which carries the rollers and the inner race, to handle combined radial and axial loads. You will find it in gearboxes, agricultural machinery, and other industrial equipment where shafts turn at moderate speeds under significant force.
The part number follows a simple pattern: a leading Y for the series, a numeric code, and a final R. For instance, Y33109R is the Y series with code 33109 and the R suffix. This lets you find the cup in the TIMKEN catalog and match it to its cone. Cup and cone are ordered separately because each has its own number.
These cups show up in food processing, cement, mining, and agriculture. They are used in gearboxes, seeders, combine harvesters, mills, conveyors, and material handling equipment. In automotive and heavy transport, tapered assemblies take simultaneous axial and radial thrust. The removable cup design makes assembly and replacement easier during maintenance.
When selecting a cup, check the outer diameter, width, and contact angle your application requires. The cup must pair with the cone of the same reference for correct roller-to-race contact. During installation, verify shaft and housing alignment, and set axial clearance per the manufacturer's recommendations. Proper lubrication and sealing help the assembly last in dusty or humid conditions.
Tapered roller cups are made to international standards, so brands can be interchanged. If you are replacing a TIMKEN cup, compare dimensions and contact angle with other equivalent brands. We can suggest a compatible alternative or source a custom cup if needed. Replacing cup and cone as a set is recommended to avoid uneven wear.

Frequently asked questions
- What is the difference between a tapered roller cup and a cone?
- The cup is the outer race that presses into the housing. The cone is the inner assembly with rollers and cage that mounts on the shaft. They are ordered separately and form the complete bearing. For best results, replace both together.
- How do I identify the TIMKEN cup I need?
- Look for the part number on the cup or housing, or provide the outer diameter, width, and contact angle. With those details we can point you to the exact reference.
- Can TIMKEN cups be interchanged with other brands?
- Yes, because tapered roller bearings follow international standards. Compare dimensions and contact angle to find an equivalent. We can advise you on a compatible option.
