<p><P>PROBLEM TO BE SOLVED: To provide a cage for a needle bearing and a needle bering, heightening lubricity and more reducing abrasion. <P>SOLUTION: The cage 16h of a thrust needle bearing 16B is formed of resin material having self-lubricity, whereby even if the cage 16h comes into contact with the steel-made raceway surface, the abrasion of the raceway surface can be restrained, the drag torque can be reduced, the weight is reduced, high speed rotation and further phenomenon of abnormal sound can be restrained. Further, the lubricating oil can be easily supplied from the inside diameter side to the center of the cage 16h through a shallow groove 16hg, so that the lubricity can be further improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
