Mechanical looseness occurs when machine components have excessive play or improper fit, leading to vibrations and potential damage. It can be classified into three main types:

• Rotating Looseness – Excessive clearance between rotating parts, such as bearings and shafts.

• Structural Looseness – Loose bolts, welds, or mounts causing instability in the machine frame.

• Component Looseness – Internal component misalignment, such as in gears or couplings.

Identifying and addressing mechanical looseness early helps prevent equipment failure and ensures optimal performance.
