n: one type of misalignment in a chain-and-sprocket drive. The shafts are not parallel to each other (they form an angle) in either the horizontal or the vertical plane. This pulls the link plates on one side tighter than those on the other side;thus, one side of the chain and sprockets wears faster than the other. Link plates on only one side of the chain break because of fatigue.

n: a type of chain alignment in which the ends of the shafts, and therefore the sprockets, are not in line with each other. Some sprockets can slide on the shaft, so it is possible for them to be misalign even if the shafts are not. Offset misalignment alternately stresses the link plates on one side of the chain and then those on the other side. Compare angular misalignment.
