Torque Tube Pivot
The Ellsworth Torque Tube Pivots ensure absolute stiffness and durability. The system utilizes oversize dual row angular contact sealed cartridge bearings. These full complement bearings were originally designed for military applications and were only recently declassified. What they offer is maximum load bearing capacity as well as the ability to fine-tune the preload to eliminate axial and radial play. Each bearing rotates on hollow 7075 pivot pins. They are custom made for each Ellsworth application and are smooth-shouldered for a perfect fit inside the inner race of the bearings. All of these factors make our Torque Tube Pivots the stiffest, most advanced pivot system in the industry.
