Pulleys must be in proper alignment or belt and bearing wear will occur.

Proper pulley alignment prevents wear on belts and bearings. When pulleys aren’t aligned, the belt is forced to track off-center, causing edge wear on the belt and possible fraying. This mis-tracking also creates uneven tension and side loads that place extra stress on the bearings, leading to premature wear and overheating. Keeping pulleys in the same plane with shafts parallel ensures the belt runs true in the grooves, distributes load evenly, and reduces vibration. In short, misalignment accelerates belt and bearing wear, while good alignment minimizes it, so the statement is true.
