State two causes of accelerated wear on one side of idler rollers?

1. Misalignment: If the idler rollers are not properly aligned with the conveyor belt, it can cause uneven wear on one side of the rollers. Misalignment can occur due to improper installation, damage to the conveyor frame, or issues with the conveyor belt tracking system.

2. Overloading: Excessive weight or pressure on one side of the idler rollers can lead to accelerated wear. This can happen if the conveyor system is not properly designed to handle the load or if there are issues with the material being conveyed. Overloading can cause the idler rollers to wear out quickly on one side, leading to uneven wear patterns.
