The RKB TQO is a two-row tapered roller bearing supplied as a matched assembly of cones and cups that share a common shaft. It handles combined radial and axial loads while maintaining rigidity in a compact envelope, which makes it a common choice for gearboxes, mining equipment and other heavy machinery.

The TQO prefix marks two-row tapered roller bearings with assembled cones and cups. References such as TQO 328003 and TQO 328015 are construction variants within that family, and the digits that follow separate sizes and internal arrangements. To match a bearing to your equipment, gather the mounting dimensions, the load capacity the position requires and the operating conditions; with those in hand, the right part number can be identified.

Typical service sectors include mining, cement, steel and heavy machinery manufacturing. These bearings appear in gearboxes, mills, crushers, cranes and material handling equipment, as well as in support rollers and the spindles of large machine tools. Their capacity for combined loads and their rigidity suit assemblies where the shaft has to stay aligned under demanding conditions.

Mounting calls for attention to shaft and housing alignment, since tapered rollers do not tolerate misalignment well. Check internal clearance or preload against the type of fit, and lubricate with grease or oil suited to the temperature and speed of the application. Sealing should keep contaminants out and the lubricant in. Follow the manufacturer's mounting and commissioning instructions and use tooling that will not damage raceways or rollers.

Replacements often bring up equivalent part numbers from other brands. Interchangeability is not automatic: even when the main dimensions agree, chamfers, fillets, load capacity and internal design can differ. Verify mounting dimensions and operating conditions before substituting a bearing. If you have another brand's reference, it can be cross-referenced to the RKB equivalent or to another option that fits the application.
