In a tapered roller bearing, the cup is the outer ring that sits in the housing and provides the raceway for the cones. It is ordered separately and matched with a cone of the same basic number to complete the assembly. The TIMKEN HH-B series is built for applications that carry radial and axial loads at the same time, such as gearboxes, drive shafts and mining equipment.

The series code begins with HH, which places the cup in a specific dimensional and capacity group within the TIMKEN tapered roller range. The following digits set the cup size, as seen in designations like HH221410-B or HH224310-B. The -B suffix denotes a construction variant of the outer ring, typically related to the radius or edge relief. To build a complete bearing, cup and cone must share the same basic number because they are made to work as a pair.

These cups appear in equipment where the shaft sees combined loading: speed reducers, conveyor belts, mills, presses, agricultural machinery and crane rails. They are common in food plants, cement plants, quarries and heavy maintenance shops. Because it is a wear part, replacement is done by part number rather than by approximate measurements; even a small change in raceway angle alters the contact pattern and shortens bearing life.

Correct selection starts with the cone that will run with the cup. The cone-cup pair is designed for a specific angle and mounting height. During installation, the cup should seat firmly in the housing without blows that could mark the raceway. Lubrication and sealing follow the environment: grease for low speed and heavy contamination, oil for high speeds. Shaft alignment between both bearings is critical so the load is distributed evenly.

TIMKEN is a well-known name in tapered rollers, and equivalents exist in other lines, but the numbers do not always cross directly. Interchange is resolved by comparing the cone and cup numbers, the mounting dimensions and the raceway angle. We can point you to a compatible alternative based on the complete designation, not on a single loose measurement.

To request a cup from the HH-B series, send the part number by WhatsApp or email. With that number we can quote the cup alone or the full cone-cup assembly. We can also advise on mounting and lubrication so the bearing performs as intended. Write with the part number or the model shown on the equipment and we will reply promptly.
