The TIMKEN tapered roller bearing cup is the outer ring that forms the assembly with the cone. It is manufactured in case-hardened and precision-ground steel, and it supports combined radial and axial loads. It is used in gearboxes, machine shafts, mining, cement and transport equipment. MR Accesorios Industriales sells this official brand line and advises you on choosing the correct cup according to the cone and the application.
The designation of this line is organized with an HM prefix, a series number and the suffix -B. For example, HM89410-B and HM231115-B correspond to HM series cups with the -B ending. The -B suffix indicates a construction variant within the family, and the central number identifies the size and mounting dimensions. The TSF series groups these components. To select the cup, the part number must be cross-referenced with the corresponding cone, which is selected separately.
These cups are used in equipment where bearings must withstand combined loads and moderate misalignment. In Argentina, they are found in speed reducers, conveyor belts, mills, cement kilns, road machinery, mining equipment and rolling mill trains. Also in railway and earthmoving applications, where robustness and durability are critical. MR Accesorios Industriales sells them for replacement and new projects.
For a correct selection, take into account the cone you are going to mount: the cup and the cone must be of the same series and diameter. Check the sealing, the internal clearance and the type of lubrication according to the environment. Alignment between shafts is essential to avoid parasitic loads. During mounting, use suitable tools and avoid striking the raceway. Cleanliness and correct lubrication extend the service life of the assembly.
TIMKEN cups are interchangeable with those of other manufacturers that follow the same dimensional standards, provided that the series, the angle and the tolerances match. Equivalences between brands are common in the market, but verification of the part number and dimensions is essential. At MR Accesorios Industriales we indicate the compatible alternative if you cannot find the exact reference. We also manufacture split plummer block housings, ANSI chains and pulleys to complete your equipment.

Frequently Asked Questions
- What is the difference between the cup and the cone in a tapered roller bearing?
- The cup is the outer ring and the cone is the inner ring with the rollers. Both are mounted together and must be of the same series and diameter. The cup is seated in the housing and the cone on the shaft. They can be replaced separately if the original combination is maintained.
- How do I know which TIMKEN cup I need for my equipment?
- You need the part number of the complete bearing or the housing and cone dimensions. With that data, we indicate the corresponding cup. If you do not have the part number, send us a photo or the dimensions on WhatsApp and we will help you identify it.
- Are TIMKEN cups compatible with other manufacturers?
- Yes, provided that the series, the angle and the tolerances match. Dimensional standards allow interchangeability between brands, but it is essential to verify the part number and the dimensions. At MR we advise you to find the compatible alternative.
