Positioned on the low-speed, high-torque shaft between the gearbox and pinion drive, the gear coupling rotates at approximately 10 RPM. The goal was to ensure that the new coupling was capable of transmitting the new, higher torques. The mill contacted several coupling manufacturers, including the original coupling OEM.

Misalignment, or the variance between the intended position and attitude of two shafts, is normally the result of manufacturing tolerances, and quantifying misalignment is crucial when seeking to specify the correct coupling. As the misalignment increases, the transmissible torque and life expectancy of the coupling reduce exponentially.

A loss in optical power will occur with lateral misalignment. This mismatch prevents some of the light from the transmit optical fiber to enter the cladding of the receive optical fiber. As the lateral misalignment increases, optical power decreases due to the loss in transmission. Lateral misalignment can occur for two reasons:
