The TIMKEN XB series tapered roller bearing cup is the removable outer race of a tapered bearing. It is press-fitted into the housing and forms, together with the cone, an assembly that supports combined radial and axial loads. It is used in equipment where clearance must be adjusted and alignment guaranteed, such as reducers, machine shafts and industrial transmissions. MR Accesorios Industriales sells it in Buenos Aires, Argentina, with more than 80 years of experience.
The XB series designation is read from the numeric part number that precedes it: for example, 07210XB and 52630XB correspond to cups of the TSF series. The XB suffix identifies a cup with specific dimensional and radius characteristics within the tapered roller family. To select the correct cup, you must start from the cone number or the complete assembly, because the cup is chosen based on the cone it will work with.
These cups are used in industries such as food, metallurgical, mining and plastics, in equipment such as conveyor belts, mixers, pumps, fans and machine tools. In Argentina, they are commonly found in speed reducers, transmission shafts and support rollers. Their ability to support combined loads makes them suitable for assemblies where the shaft works with radial and axial forces at the same time.
For mounting, keep in mind that the cup is installed in the housing with an interference fit and must be perfectly seated against the shoulder. Adequate lubrication and sealing prevent contamination and extend service life. Axial clearance is adjusted by moving the cone on the shaft or by means of shims; incorrect alignment causes premature wear. Always verify that the cup and cone are of the same series and manufacturer to ensure correct roller contact.
Regarding equivalences, tapered roller cups are identified by their part number, which may vary between manufacturers. To replace a TIMKEN cup with another brand, it is essential to compare outer dimensions, width and contact angle. It is not enough for the part number to be similar. If you need an alternative, at MR Accesorios Industriales we will indicate the compatible option with the exact dimensions of your equipment.

Frequently Asked Questions
- What is the difference between the cup and the cone in a tapered bearing?
- The cup is the removable outer race and the cone is the inner assembly with the rollers. They are mounted separately and adjusted to each other. To replace, both must be changed if they are worn.
- How do I know which TIMKEN cup I need for my equipment?
- You need the part number of the complete bearing or the cone. With that data, we will indicate the corresponding cup. If you don't have it, we can help you identify it with the housing dimensions.
- Can I replace a TIMKEN cup with another brand?
- Yes, as long as the outer dimensions, width and contact angle match. Don't rely only on the part number. At MR we advise you to find the compatible alternative.
