The shaft run-out in a V-belt drive system should be no more than __________.

In a V-belt drive system, maintaining proper alignment and minimizing shaft run-out is crucial for efficient operation and longevity of the components. The specified limit for shaft run-out is 0.002 inch, as this tight tolerance helps to reduce vibration and wear on the belts and pulleys. A run-out exceeding this value can lead to uneven wear, increased friction, and even potential failure of the drive system over time. Therefore, 0.002 inch is the maximum allowable run-out that ensures smooth operation, optimal performance, and extends the service life of the V-belt drive system.
