The TIMKEN TSF series tapered roller bearing cup is the removable outer ring of a tapered roller bearing. It mounts in the housing and works together with the cone to support combined radial and axial loads. It is used in equipment where force must be transmitted precisely and thrusts must be supported, such as gearboxes, machine shafts and conveyor rollers. MR Accesorios Industriales supplies it in Buenos Aires, Argentina.

The designation of this series is read as the base number followed by the suffix -B, which identifies the cup within the TIMKEN system. For example, references 332-B, 354-B, 362-B and 382-B correspond to cups of different dimensions, and the same applies to 432-B, 453-B, 472-B and 493-B. The -B suffix does not indicate dimensions by itself, but is part of the code that must be matched with the corresponding cone to assemble the complete bearing. The TSF series groups these tapered roller cups.

These cups are used in industries in Argentina such as food, cement, mining and metallurgy. They are present in gearboxes, conveyor belts, mills, mixers and agricultural machinery. They are also used in material handling equipment and in transmission shafts where combined loads require a tapered roller bearing. Since the cup is the outer part, it is press-fitted into the housing and receives the thrust from the cone, which rotates with the shaft.

To select the correct cup, start from the complete code of the bearing or of the cone to be replaced. The cup and the cone must be of the same series and diameter to ensure correct roller contact. During installation, check the alignment of the housing and the seat, and lubricate with the grease or oil recommended for the application. Proper sealing prevents contamination and extends the service life of the assembly. If you have doubts, send us the code and we will indicate the compatible alternative.

Regarding equivalences, tapered roller bearings are identified by designation systems that may vary between manufacturers. A TIMKEN cup may have equivalents in other brands, but interchangeability depends on the dimensions and tolerances of the cone-cup assembly. It is not enough for the number to be similar: the outer diameter, width and contact angle must be compared. Therefore, for replacements, the safest approach is to request a quote with the exact code or with the dimensions of the original bearing.
