PURPOSE: To improve an operating characteristic of a bearing by allowing second end parts of plural rollers arranged in axially inclined annular rows to engage with the adjacent roller second end parts, and extending guide member protrusions to between first end parts of the adjacent rollers to circumferentially separate the first end parts. CONSTITUTION: In a roller bearing using this roller guide member 86, rollers 54 are arranged in annular rows within race spaces, while the respective rows are oppositely axially inclined such that each the row is axially tapered outward. As a result, inner hubs 58 of the rollers 54 are circumferentially apart from small-diameter outer hubs 62, while the respective outer hubs 62 contact with the adjacent rollers 54. The number of the rollers 54 in the respective rows is set to the maximum to fully use the race spaces. Protrusions 110, 114 of the guide member 86 between the rows of the roller 54 separate inclined surface parts 102 in both side surfaces 94, 98 of a ring 90. Because the rollers 54 are respectively received in pockets 126 and seated in the inclined surface parts 102, the rollers 54 are skewed to show a constant one-way progression or indexing movement characteristic in the case of accompanying vibration. |
