<p><P>PROBLEM TO BE SOLVED: To process and assemble with higher precision by a usual metal cutting machining tool even in a retainer of a large-sized bearing, and to solve the excessive friction between the retainer and a roller without improving the precision in a pocket shape of the retainer even in a resin-made retainer. <P>SOLUTION: The separator retainer 1 is interposed between respective rollers 4. A pillar 2 of the separator retainer 1 has an axial slit 2a. The depth of the slit 2a is shaped to stride the P.C.D. of the roller 4 (rolling element). Thereby, even when the circumferential expansion amount of the separator retainer 2a is bigger than the roller 4 as the temperature increases, the slit 2a elastically deforms toward the circumferential inside, so that the expansion amount of the roller 4 and the separator retainer 1 can be absorbed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
