What should the alignment tolerance be based on?

The alignment tolerance should be based on the specific application and the manufacturer's specifications because different machines have varying operational demands and specifications that dictate acceptable alignment limits. Each type of machinery is designed to perform effectively under certain conditions, and these specifications are crucial in ensuring the machinery operates safely and efficiently.

Manufacturer's guidelines often include tolerances that account for factors such as load, speed, and vibration. Adhering to these guidelines helps prevent excessive wear, reduce the risk of failure, and maintain optimal performance. Therefore, a thorough understanding of the specific requirements of the application and following the manufacturer's recommendations is essential for achieving proper alignment and ensuring long-term reliability and efficiency of the machinery.

Other factors, like the size of the machinery, environmental conditions, or the cost of alignment tools, may influence the alignment process but do not set the fundamental tolerances required for proper alignment.
