Double row tapered roller bearings feature two sets of tapered raceways and tapered rollers, and therefore have higher load carrying capacities and higher stiffness. Furthermore, the raceways and rollers on the two rows are tapered in opposite direction so they can carry axial loads in both the directions.
Depending on the taper direction of the raceway and roller rows, AEC double row tapered roller bearings are available in the following two designs:
TDI Design
Bearings in this design have the two rows of tapered rollers and raceways arranged back-to-back. They have two outer rings or cups and one double row inner ring or cone. Generally, a cup spacer is placed between the two outer rings to provide certain axial clearance or preload.
TDO Design
Bearings in this design have the two rows of tapered rollers and raceways arranged face-to-face. They have one double row outer ring or cup and two inner ring or cones. Generally, a cone spacer is placed between the two inner rings to provide certain axial clearance or preload.
