What is runout in a mechanical drive system?

Explanation:
Runout is about the geometry of rotation. When a shaft, pulley, or wheel isn’t perfectly centered or coaxial, it doesnels off the true axis as it spins, creating a wobble or off-center motion. This deviation from the true rotation axis leads to vibrations, uneven wear, and inconsistent motion in a mechanical drive system. It’s different from variation in belt tension (which is a force issue, not the path of the rotating part), gear backlash (the clearance between teeth), or the rate of horsepower output (power, not alignment). So the description that fits runout is the deviation from the true rotation axis.
