摘要: A roller bushing assembly (21d, 21e, 21f) designed to enable a low tolerance, frictional fit within an out-of-round or otherwise distorted support member (5, 9) includes (29a, 216) having outer surface (102) machined provide various axially spaced, annular grooves (127-130, 132 and 242-250). Between directly adjacent respective ones of the 242-250) are defined plurality spaced radially extending ribs (113-122 232-240). The axial outermost (113, 122 240) preferably elongated relative remaining (114-121 232-239) have annularly chamfered portions (124, 125 252). 232-240) adapted shear upon mounting support. By providing shearable 232-240), can be effectively mounted greater range varying sized members. In accordance with first embodiment, constitutes sleeve (29a) which is at least one bearing unit (33, 34). shearing (113-122) assures that 34) will not excessively pre-loaded in radial direction. second pin (216) formed terminal stub shafts (222 223) units (186) positioned pockets (182, 183) pair shackle links (164, 165).
