Tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions. 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. Double- or two-row   tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications. 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 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.
