ROLLER BEARING |
摘要 |
<p>A roller bearing having spacers interposed between its rollers is provided, which has a high permissible rotational speed which is achieved by allowing a lubricant to flow smoothly around rolling surfaces so that the stirring resistance of the lubricant due to the spacers is reduced. The roller bearing includes: a plurality of rotatable rollers (16) interposed between an inner ring raceway surface and an outer ring raceway surface; and spacers (18) provided between adjacent rollers (16). Each of the spacers (18) includes extended portions (18a) facing roller end faces (16b) at both axial ends thereof.</p> |
