This utility model relates to the field of yarn feeder technology, and discloses a guide roller assembly and a yarn feeder for a high-speed, multi-path yarn feeder. The guide roller assembly includes a bearing B, a bearing A, a roller, a mandrel, an elastic washer, and fixing screws. Bearing B is a floating bearing. An O-ring is added to the mandrel at the location of the floating bearing B. By changing the depth of the groove of the O-ring and the matching of the O-ring wire diameter, suitable friction can be obtained, stabilizing the static state of the inner ring of the floating bearing B, avoiding wear between the inner ring of bearing B and the mandrel, and ensuring that the bearing is always in a normal working state. This guide roller assembly has a simple structure and stable improvement effect.
