The cup is the removable outer ring of a tapered roller bearing. It is press-fitted into the housing and, together with the cone — the inner ring with the rollers — forms an assembly that supports combined radial and axial loads. It is used in gearboxes, wheel hubs, agricultural machinery and industrial equipment where precision and load capacity are critical. MR Accesorios Industriales supplies the TIMKEN brand in Buenos Aires, Argentina.

The designation of this line combines an initial letter, a numeric series and a suffix. In the examples A2126-B, A4138-B and A6157-B, the letter A identifies the cup family, the numbers define the size and the suffix -B distinguishes a construction variant within that series. To choose the correct cup, the complete part number must be respected: each combination corresponds to a specific outer diameter and width that must match the cone and the housing.

These cups are used in applications where the bearing operates under combined load and requires separate adjustment. They are commonly found in gearboxes and gear cases, wheel hubs of road and agricultural equipment, machine tools, process pumps and conveyors. In the Argentine market, the metalworking industry, agro-industry and the mining sector are the main users of this tapered roller line.

To select a cup, start from the cone you already have mounted or from the complete bearing part number. The cup and the cone are chosen as a set: one is not replaced without verifying the other. Mounting is done with a press or controlled heating, never by striking the raceway. Lubrication and housing sealing determine service life; it is advisable to use grease or oil compatible with the operating temperature and to check axial clearance according to the equipment manual.

TIMKEN is a world reference in tapered roller bearings and its nomenclature cross-references with that of other manufacturers. In general, equivalences are established by dimensions — outer diameter, width and raceway angle — and not by part number. If you need to replace a cup from another brand, send us the measurements or the original part number and we will indicate the compatible alternative within the TIMKEN line we supply.

To request a quote for your TIMKEN cup, send the complete part number by WhatsApp to MR Accesorios Industriales. If you have doubts about the designation or are looking for a variant that does not appear, write to us with the model or measurements and we will reply promptly. We can also advise you on the corresponding cone and the mounting criteria for your application.
