The TIMKEN tapered roller bearing cup is the removable outer ring of a tapered roller bearing. It is press-fitted into the housing and forms the raceway for the rollers and the cone. It is used in applications with combined radial and axial loads and requires precise alignment. MR Accesorios Industriales carries this line for plants and workshops throughout Argentina.
The designation of this cup is read from its numeric code followed by the suffix -SA, which identifies the series and the raceway design. For example, 553-SA corresponds to a cup of the 553 series with SA ending. The SA suffix indicates a design variant within the tapered roller family. To choose the correct cup, the code must be matched with the corresponding cone, which is the inner part of the bearing.
These cups are used in power transmission equipment, gearboxes, pumps, fans, conveyors and agricultural machinery. In Argentina they are common in the food, cement and mining industries and in fleet maintenance workshops. Their ability to support simultaneous radial and axial loads makes them suitable for wheel hubs, spindles and transmission shafts with moderate to high demands.
To select a TIMKEN cup, consider the outer diameter, the width and the raceway angle, which must match the cone. Mounting is done by press fit into the housing, with suitable tools so as not to damage the raceway. It is essential to verify alignment and lubrication: an adequate film of oil or grease extends service life. Sealing the assembly prevents contamination by dust or moisture.
Tapered roller cups are interchangeable between brands if the standardized dimensions and the contact angle match. TIMKEN is a world reference, and equivalents from other firms exist on the local market. To replace a cup, the safest approach is to compare the complete code and the actual dimensions. MR Accesorios Industriales can tell you the alternative compatible with your application.

Frequently Asked Questions
- What is the difference between a cup and a cone of a tapered roller bearing?
- The cup is the removable outer ring, which is mounted in the housing. The cone is the inner ring with the rollers and the cage, which goes on the shaft. Both form the complete bearing and must be of the same series to work correctly.
- How do I know which TIMKEN cup I need for my equipment?
- You need the code engraved on the original part or the dimensions of the housing and the cone. With those data we will quote you the equivalent cup. If you do not have the code, send us a photo or the dimensions on WhatsApp and we will help you.
- Can TIMKEN cups be replaced by other brands?
- Yes, as long as the standardized dimensions and the contact angle match. Equivalents from other brands exist. To ensure interchangeability, compare the complete code and verify the actual dimensions before mounting.
