In a tapered roller bearing, the cup is the outer ring that can be taken out of the assembly. It sits in the housing, while the cone rides on the shaft. Working as a pair, they carry combined radial and axial loads. MR Industrial Accessories LLC supplies TIMKEN cups to customers throughout the United States and in several Latin American countries.

Reading the designation helps you order the right piece. The base number points to the series, and the D suffix marks a cup with particular dimensions inside that series. Cups such as 672D, 773D, 854D and 98789D each mate with their matching cone. The safest starting point is the cone or the complete assembly number already running on your equipment. Send that number and we will quote the cup that belongs with it.

These cups suit equipment that sees combined loads and needs rigidity: gear reducers and gearboxes, conveyor rollers, agricultural machinery, road equipment, cranes and bridges, and machine tool spindles. They are common in food, cement, steel, mining and agricultural plants, as well as in fleet maintenance and earthmoving work. Where impact or vibration is present, a tapered roller cup is a solid choice.

Selection comes down to load type, speed and the conditions around the equipment. The cup is pressed into the housing with an interference fit, and the cone goes onto the shaft. Alignment and axial clearance matter and are set during assembly. Lubrication has to be right, and sealing keeps dust or moisture out of the bearing. In high-temperature service, check the dimensional stability of the cup. If anything is unclear, ask us with the part number in hand.

Designation systems differ from one manufacturer to the next, so cups are identified by standards and codes that do not always line up. TIMKEN uses its own nomenclature, while other brands use equivalent codes. Interchangeability is not automatic: dimensions, angle and load capacity all have to be compared. Give us the original part number and we will point you to the compatible alternative, working from the exact designation and standardized dimensions.
