The TIMKEN HH series tapered roller bearing cone is the inner race, with its rollers and cage, of a high-capacity tapered roller bearing. It is used together with the matching cup to support combined radial and axial loads in heavy-duty equipment. It is a key component in gearboxes, mining machinery, steelmaking and transport equipment, where high load and rigidity demands apply.

The HH series designation is read in blocks: the initial letters identify the cone family and the number that follows defines the size and geometry of the race. The C suffix, as in HH421246C, indicates a construction variant within that family. To choose the correct assembly, the cone part number must be matched with the cup part number: both form the complete bearing and are not interchangeable with each other. If you have the part number stamped on the component, send it exactly as is.

In Argentina these cones appear in large gearboxes, mills, conveyor belts, mining and quarry equipment, rolling mill trains and heavy agricultural machinery. They are also found in railway and port applications where the bearing works under combined load and shock. The HH series, due to its section and capacity, is reserved for shafts of considerable diameter and high rigidity requirements, not for light assemblies.

To select correctly, you must define the radial and axial load, the rotation speed and the type of lubrication. During assembly, the cone and cup are fitted with controlled interference and the axial clearance is set according to the equipment manual; poor alignment or incorrectly adjusted clearance shortens bearing life. Sealing and lubricant cleanliness are critical in dusty or wet environments.

Interchangeability between brands is resolved by dimensions and by the cone-cup pair, not by the commercial part number. The same size may exist in different brands with their own nomenclatures, and substitution requires comparing bore, width and contact angle. At MR Accesorios Industriales we indicate the compatible alternative or manufacture it to measure when the case requires it.

If you need this cone or its complementary cup, write to us on WhatsApp with the complete part number, for example HH421246C, and we will quote it promptly. We can also advise you on the cone-cup pair that corresponds to your equipment and on the appropriate lubrication for the application.
