摘要： An anti-ghosting roller having a main shaft, an inner race detachably mounted on the main shaft, a rotary bearing having movable bearing elements (e.g., needle bearings) positioned on the inner race, a roller core secured to the rotary bearing, and an end collar mounted to the shaft and spaced from an end of the roller core such that the roller core can both rotate and axially oscillate relative to the main shaft. The inner race extends beyond the end of the rotary bearing. An end collar is mounted to the end of the shaft. The end collar includes a spacer portion extending axially toward the roller core. The spacer portion is radially spaced from the main shaft so that it is free from interaction with the inner race.
