A tapered roller bearing cup is the outer race of the assembly. This TIMKEN TSF series cup, identified by the code YSA30308RM, is made to carry combined radial and axial loads where precision and durability matter. It works as a pair with the matching cone to locate and support rotating shafts in industrial machinery. MR Industrial Accessories supplies this cup within its bearing range for maintenance and replacement work.
The TSF designation is read from the full reference. In YSA30308RM, the prefix points to the cup design and the numeric block sets the size. The TSF family covers cups built to a particular geometry for assemblies that need high load capacity. When ordering, use the exact code stamped on the original bearing or listed in the equipment manual rather than a partial reference.
These cups turn up in gearboxes, drive shafts, mining equipment, mills, presses and agricultural machinery, as well as in conveyor rollers and machine tool spindles. Their job is to take the combined radial and axial loading that comes from helical or bevel gears and from wheels running on a rail.
During installation, check that the cone and cup carry the same series number, because the two are ground as a set. Careful alignment between them helps avoid early wear. The right lubricant, grease or oil depending on the environment, together with effective sealing against contaminants, supports a longer service life. On equipment subject to vibration or shock, use the internal clearance specified by the machine builder.
Cups from different brands may be interchangeable when dimensions and contact angle line up, but not every series is equivalent. On a replacement job, compare the full code and the main dimensions. Our team can help you find the cup that fits your assembly and steer you away from failures caused by a wrong selection.
To request the TIMKEN TSF series cup, send the code YSA30308RM or the code of the complete bearing by WhatsApp or email. We reply promptly with a quote and, if needed, point you to a compatible alternative.

Frequently asked questions
- What separates a cup from a cone in a tapered roller bearing?
- The cup is the outer race; the cone is the inner assembly that holds the rollers. They are fitted separately and need the same series number to work correctly. Swapping just one part without checking the other can shorten bearing life.
- How can I tell if the TIMKEN YSA30308RM cup fits my equipment?
- Match the full code and the main dimensions against the original bearing. If anything is unclear, message us on WhatsApp with the equipment model or a photo of the part and we will help you identify the right cup.
- Which lubricant should I use on tapered roller bearings?
- It depends on speed, temperature and environment. As a rule, high-pressure grease or oil with EP additives is used. Follow the equipment manufacturer's instructions and keep a constant lubricant film. We can advise based on your application.
