ABSTRACT:
A roller for a bearing used in a linear movement rolling guide apparatus is tumbled after superfinishing the outer peripheral surface so that the surface roughness of the roller in a circumferential direction is in a range from 0.05 to 0.10 micrometers in average roughness on the center line. The surface roughness in the circumferential direction of the outer peripheral surface of the roller is substantially equal to or slightly larger than the surface roughness in the axial direction of the outer peripheral surface to thereby prevent the occurrence of micro-slip.
