ABSTRACT:
A precision centerable, rotatable shaft assembly (60) has a shaft (62) and a housing (64) extending generally axially along the shaft (62). The shaft (62) is journalled to the housing (64) by a first roller bearing assembly (66) and a second roller bearing assembly (68). The first roller bearing assembly (66) is connected to the shaft (62) near end (80) and a second roller bearing assembly (68) is connected to the shaft (62) near end (83). The first roller bearing assembly has a first inner race (70) fixedly attached to the shaft (62) and a first outer race (74) fixedly attached to the housing (64). The outer race has an inner surface (78) tapering toward the shaft (62) approaching the end of the shaft (62). The second roller bearing assembly has a second inner race (82) fixedly attached to the shaft (62) and a second outer race (86) axially movable within the housing (64) toward the first roller bearing (66). The second outer race (86) has an inner surface (91) tapering away from the shaft (62) moving toward the first roller bearing assembly (66). A flange (94), rod (96) and micrometer (100) are attached to the second roller bearing assembly (68) so that adjustment of the micrometer (100) moves the second outer race (86) downward within housing (64) to compensate for wear of the bearing assemblies (66) and (68) in use of the rotatable shaft assembly (60).
