The TIMKEN TSF series tapered roller bearing cup is the outer race of a tapered roller bearing, manufactured to withstand combined loads —radial and axial— in assemblies where precision and durability are critical. It is used together with the matching cone to form an assembly that guides and supports rotating shafts in industrial equipment. MR Accesorios Industriales sells this cup as part of its bearing line for maintenance and replacement.
The TSF series designation is read from the complete code: for example, YSA30308RM combines a prefix that identifies the cup design and a number that defines the size. In practice, the TSF designation groups tapered roller cups with a specific geometry for assemblies that require high load capacity. To select the correct cup, take into account the exact code shown on the original bearing or in the equipment manual.
In Argentine industry, these cups are used in gearboxes, drive shafts, mining equipment, mills, presses and agricultural machinery. They also appear in conveyor rollers and machine tool spindles. Their function is to support loads that combine radial and axial stress, typical of helical or bevel gears and of wheels in contact with the rail.
For assembly, verify that the cone and cup share the same series number, since they are ground as a set. The alignment between the two must be careful to avoid premature wear. Proper lubrication —grease or oil depending on the environment— and effective sealing against contaminants extend service life. If the equipment operates with vibration or shock, choose the internal clearance recommended by the equipment manufacturer.
Tapered roller cups from different brands can be interchanged if the dimensions and contact angle match, but not all series are equivalent. Therefore, when replacing, compare the complete code and the main dimensions. At MR Accesorios Industriales we advise you to find the cup compatible with your assembly and avoid failures caused by an incorrect selection.
If you need the TIMKEN TSF series cup, send us the code YSA30308RM or the code of the complete bearing via WhatsApp. We'll send you a quote shortly and indicate the compatible alternative if needed. With more than 80 years in the market, MR Accesorios Industriales is your partner for keeping production running.

Frequently Asked Questions
- What is the difference between a cup and a cone in a tapered roller bearing?
- The cup is the outer race, while the cone is the inner assembly with the rollers. They are mounted separately and must share the same series number to guarantee correct operation. Replacing only one part without verifying the other can shorten bearing life.
- How do I know if the TIMKEN YSA30308RM cup is compatible with my equipment?
- Compare the complete code and the main dimensions with the original bearing. If you have doubts, message us on WhatsApp with the equipment model or a photo of the part and we'll help you identify the right cup.
- What lubrication do you recommend for tapered roller bearings?
- It depends on speed, temperature and environment. In general, high-pressure grease or oil with EP additives is used. Follow the equipment manufacturer's instructions and ensure a constant lubricant film. If you need it, we advise you according to your application.
