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.
Four-Row Tapered Roller Bearings
Four-row bearings combine the inherent high-load, radial/thrust capacity and direct/indirect mounting variables
of tapered roller bearings into assemblies of maximum load rating in minimum space.
