Idler Pulley

Advanced Usage:
In more technical discussions, the idler pulley may be referred to in the context of "belt drive systems" or "tensioning mechanisms." Engineers might discuss the "tension ratio" or "pulley alignment" concerning the idler pulley to optimize performance.
Word Variants:
- Idler: This can refer more generally to something that does not take an active role or is inactive. For example, "He's often seen as an idler in the office." - Pulley: This can refer to any wheel on an axle designed to support movement and change direction of the force.
