Excessive movement in bearings can lead to an increase in maintenance costs. This is primarily due to the wear and tear that occurs when there is improper alignment or excessive play in the bearings. Over time, this can result in more frequent repairs, replacement of parts, or complete machinery failure, all of which contribute to higher operational and maintenance expenses. When bearings are not stable, they can cause misalignment in the connected machinery, leading to inefficiencies and further costs related to downtime and labour.

On the other hand, an extended equipment lifespan, improved energy efficiency, and stable machine performance are not typically associated with excessive movement in bearings. Instead, effective and proper bearing function contributes to enhanced operational reliability, reduced friction, and overall efficiency, helping to minimize costs and extend the life of the equipment.
