Gearbox Misalignment: Signs and Causes - Motion Control Tips
Parallel misalignment is the distance between the shafts' axes of rotation, measured at the plane of power transmission (typically the center of the coupling), and is expressed in mils (1 mil = 0.001 inch) or mm. Angular misalignment is the difference in the slope of one shaft relative to the slope of the other shaft, expressed in mil/inch or ...

How to prevent conveyor belt damage? - SKE
The most common cause of conveyor belt damage is the transfer of sharp conveyed material. Other reasons include: skirting improperly adjusted or made of the wrong material; material hang up in or under the chute; clogged or misaligned rollers; material spillage or build up; or excessive belt sag between idlers causing the load to work and shuffle on the belt as it passes over idlers.
