Abstract
In a guide roller assembly such as utilized for supporting a reciprocating yarn guide rod in a textile winding machine, the guide roller assembly having an outer shell rotatably supported on a carrier member by an interposed ball bearing assembly, problems of internal contamination of the guide roller assembly are avoided by provision of a plurality of annular projecting walls on one or both of the outer shell and the carrier member to define narrow annular spacings between the outer shell and the carrier member at the annular walls and annular air chambers in radial series between the walls. The narrow annular spacings are preferably of a maximum dimension in the range of a few tenths of a millimeter. Debris entering the interior of the guide roller assembly tends to be propelled radially outwardly and accumulates at the annular spacings to resist entry of further debris.
