PURPOSE: To manufacture a bearing compactly and economically, by providing at least one recessed part having two circumferentially facing boundary walls in an outer race, and by tightly engaging a projection circumferentially fixed to a support member between the boundary walls. CONSTITUTION: Bearing outer races 6, 7 have two groove-shaped recessed parts 35 mutually facing in their diameter direction, and each recessed part 35 has two flat boundary walls 36 which radially extend and circumferentially face each other. Each end 34 (projection) of a cylindrical pin 33 is tightly engaged between the both boundary walls 36. A long groove 37 that extends in the axial direction and communicates with a supply hole 38 is drilled in a support hole 2 in a support member 1. Lubricating oil is sent from the supply hole 38 to the recessed part 35 through the long groove 37, and then sent to an non-illustrated rolling element inward in the radial direction. When the outer races 6, 7 relatively move slightly in the radially load direction, the end 34 of the cylindrical pin 33 slides along the radial boundary wall 36 of the recessed part 35. |
