In a tapered roller bearing, the cone is the inner ring that carries the rollers and the cage. It works together with the cup, the outer raceway, to handle radial and axial loads in one direction. The XA series uses a suffix to indicate a design variant within the family. MR Industrial Accessories LLC supplies this TIMKEN line to customers throughout the United States and Latin America.

The XA designation combines a numeric code with a letter suffix. Take 683XA: the digits define the size and geometry of the cone, while XA points to a specific construction variant in the series. Because cone and cup are matched as a pair, this coding lets you find the exact cone for a given cup. When ordering a replacement, always provide the full part number as marked on the original bearing.

These cones are found in equipment that sees combined loads: gear reducers, transmission housings, axle assemblies on road and earthmoving machines, conveyors, and agricultural implements. They also appear in maintenance work at aggregate plants, mills, and industrial transmissions. Internal clearance can be set during mounting, which helps them suit different load and speed conditions.

Selection starts with the cup: the cone must be mounted with its corresponding cup, and the two are not interchangeable between assemblies. Check the sealing arrangement, the lubrication method, and the axial clearance specified by the equipment builder. During installation, proper raceway alignment and clean working conditions help avoid early failures. If you replace only the cone, inspect the cup and rollers before reassembly.

For equivalences, tapered roller bearings are identified by the assembly number or by the cone-and-cup combination. Brands may list similar dimensions, but interchangeability depends on matching tolerances and contact angle. The reliable way to choose an alternative is to compare the original part number and the mounting dimensions. Send us the part number and we will point you to a compatible option.
