A circular knitting machine has a needle cylinder, a supporting disk attached to the needle cylinder coaxially therewith, a bearing body for the supporting disk surrounding the supporting disk, four bearing tracks arranged opposite one another in pairs on the supporting disk and on the bearing body, and bearing balls supported on the bearing tracks. Two elastic supporting flanges, each having one bearing track of two axially adjacent bearing tracks formed thereon, are provided to compensate radial expansions.

A circular knitting machine comprising a needle cylinder, a supporting disk attached to said needle cylinder coaxially therewith, a bearing body for said supporting disk surrounding said supporting disk, four bearing tracks arranged opposite one another in pairs on said supporting disk and on said bearing body, and bearing balls supported on said bearing tracks, one pair of said bearing tracks being arranged on a pair of supporting flanges capable of deflecting elastically in order to compensate radial expansions said supporting flanges carrying wire rings having circular cross-sectional areas and said bearing tracks being ground hollow into all of these wire rings with a circular profile defined by a circular arc and with a radius larger than the radius of said bearing balls, said bearing tracks on said wire rings carried by said elastically deflecting supporting flanges being eccentrically ground with respect to the center of said bearing balls, the center of said circular arc defining said hollow-ground circular profile being offset laterally by a certain distance (S) from the diameter of said bearing balls, the extension of which diameter passes through the center of said circular cross-sectional area of the adjacent wire rings, such that upon deflection of said elastically deflecting supporting flanges, said bearing balls do not run on edges of said hollow-ground wire rings.
