Disclosed is a top roller for use in a fine or rough spinning frame wherein a plurality of rollers or balls are fitted into one of two axially spaced apart annular grooves formed in the exterior side wall of a rotary section of an arbor and retained with a first retainer in circumferentially equidistantly spaced apart relation and are made into direct rolling contact with the interior side wall of a rotary shell with a rubber cot fitted over the rotary section of the arbor, another plurality of rollers or balls are fitted into the other annular groove of the rotary section of the arbor and a complementary annular groove formed in the interior side wall of the rotary shell and retained with a second retainer in circumferentially equidistantly spaced apart relation, and a bearing chamber housing the rollers or bearings between the rotary section of the arbor and the rotary shell is sealed with a cap with an oil hole at one or outer end and with a flanged seal and a shielding ring at the other or inner end. For lubrication lubricant feeding blades are formed integral with the retainer adjacent to the cap and oil supply passages are extended through the arbor between the free ends thereof in opposed relation with the oil hole of the cap and a point intermediate the two annular grooves at the exterior side wall of the rotary section of the arbor. A method for assembly of the top rollers with the above construction is also disclosed. |
