What are possible causes of misalignment aside from installation errors?

Misalignment can occur due to several factors beyond initial installation errors, and the selection correctly identifies a range of these causes. Equipment wear is a fundamental reason; as components of machinery age and experience operational stress, they may succumb to wear and tear, leading to shifting or misalignment over time.

Thermal expansion is another significant factor. Many materials undergo expansion or contraction in response to temperature changes. In operational environments where machinery heats up during use, this fluctuation can cause components to move and lead to misalignment as different parts expand at varying rates.

Additionally, foundation settling can play a critical role in alignment issues. Over time, the support structure or foundation on which the equipment rests can settle unevenly due to weight, environmental factors, or soil conditions. This settling can cause alterations in the position of the machinery, resulting in misalignment.

These combined causes illustrate the importance of regular maintenance and monitoring beyond the initial installation process, reinforcing the need for ongoing alignment checks throughout the lifespan of equipment.
