|TNA bearings are similar to the TDO, but the inner race narrow faces are extended to abut and eliminate the need for a separate inner race spacer. Supplied with an in-built clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications where simplicity of assembly is required. | |TNA bearings are similar to the TDO, but the inner race narrow faces are extended to abut and eliminate the need for a separate inner race spacer.

Single Row Bearing
Inch Single Row
Single-row tapered roller bearings are the most basic and widely used, consisting of a cone assembly and a cup. Timken patented the first in 1898 and today offers the world's widest variety in inch and metric sizes.
Metric Single Row
The company continues to extend its line of Timken® single row metric tapered roller bearings to respond to customer needs and today offers one of the industry's broadest ranges of metric parts.
Double Row Bearing
Inch Double Row
Double- or two-row Timken® tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications.
Metric Double Row
Timken features one of the industry's largest selections of metric tapered roller bearing matched assemblies. With industry standard part numbering, it's now easier to find the bearing you need.
Four Row Bearing
Timken® four-row tapered roller bearings combine the inherent high-load radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings into assemblies offering maximum load rating in minimum space.
Integrated Bearing Assemblies
Timken® integrated bearing assemblies are the result of our collaborations with customers to design, engineer and test a continuous stream of next-generation solutions, including AP-2™ bearings for rail applications.
