Gear bearings are, as their name implies, a combination of both gear and bearing functions in one component. Like gears, they feature teeth that intermesh with one another, and like bearings they do so to transfer radial and axial loads to bear weight and friction. Gear bearings improve drives in electrical, internal combustion, and turbine motors. The gear bearing design incorporates rifle-true anti-backlash, improved thrust bearing performance, and phase-tuning techniques for superior low-speed reduction. Because they combine both gear and bearing functions, gear bearings can reduce weight, number of parts, size and cost, and increase load capacity.
