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.
