The term describes indentations in the race circumferential face, spaced identically to the roller bodies. The damage affects the individual gear's bore and race, and the roller bodies. This type of damage is serious due to a very high increase in radial play on helically-cut gears. It can result in contact pattern displacement on the mating gears and can culminate in tooth failure.
