Abstract
A bushing used in a machine for scoring or slotting sheets of material using rotating wheels. The bushing, which is used to move a rotating scoring or slotting wheel in an axial direction, includes a housing configured for support by a yoke that moves axially to impart axial movement to the wheel while the wheel rotates. The bushing also includes a sacrificial end cap, which is supported by the housing, that is configured for replacement without replacing the housing. Each yoke typically supports a number of such bushings, and bushing typically supports a pair of sacrificial end caps to permit bidirectional movement of the rotating wheel. Shims may also be placed between an end cap and its associated housing to offset wear of the end cap.
