Double Row Tapered Roller Bearing

Timken double-row non-adjustable (TNA) bearings feature extended inner race narrow faces that eliminate the need for a separate inner race spacer. This innovative design reduces assembly time and complexity, making it ideal for high-performance machinery. Supplied with an in-built clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications in sectors such as manufacturing, mining, construction equipment, and power transmission systems.

These bearings have one-piece double inner race and two single outer races and are typically supplied complete with an outer race spacer as a pre-set assembly. They can be used at fixed positions on rotation shaft applications or float positions for rotating housing applications on the stationary shaft.

Timken tapered roller bearings with double outer race (TDO) deliver exceptional stability, high load-carrying capacity, and long service life in demanding industrial applications. Featuring two rows of tapered rollers and a double outer race, Timken TDO bearings efficiently manage combined radial and axial loads, making them ideal for gearboxes, conveyors, and heavy machinery.

These bearings consist of two single-row bearings with individually matched spacers that are set at the factory to pre-determined dimensions and tolerances. Matched bearing assemblies are used in applications requiring higher load carrying capacity or where the shaft must be located axially in both directions with a specific axial clearance or preload.
