F=raceway diameter of innerring. Fw=needle roller enveloping circle in the tolerance zone F6. 2)The basic load ratings C and C0 apply if the bearing outerring(with cylindrical outside surface) is mounted in a housing bore with the normal rolling bearing fit; when used as a track roller,the load ratings Cw and Cow apply. 3)Limiting speed for grease lubrication.with oil lubrication,the speed can be increased by approximately 30%.
