1 . A circular knitting machine, comprising a frame; a dial cam support mounted in said frame; a dial cam fastenable to said dial cam support; a dial cam shaft rotatably and coaxially mounted in said dial cam support; and a dial rotatably and coaxially mounted on said dial cam support with an adjustable bearing clearance and driven by said dial cam shaft. 
   
   
       2 . A circular knitting machine as defined in  claim 1 , further comprising a spring plate by which said dial is connected coaxially to said dial cam shaft. 
   
   
       3 . A circular knitting machine as defined in  claim 1 , wherein said bearing contains a plurality of bearing balls which on one side run on bearing surfaces of said dial cam support and on the other side run on bearing surfaces associated with one another of a holding ring provided on said dial and a bearing ring connected thereto. 
   
   
       4 . A circular knitting machine as defined in  claim 1 , wherein said bearing is a wire ring roller bearing. 
   
   
       5 . A circular knitting machine as defined in  claim 1 , further comprising a screw connection provided between said holding ring and said bearing ring for adjustment of said bearing clearance. 
   
   
       6 . A circular knitting machine as defined in  claim 3 , wherein said dial is detachably connected to said holding ring. 
   
   
       7 . A circular knitting machine as defined in  claim 4 , wherein said bearing surfaces are provided on wire rings, which are arranged in pairs opposite one another on said dial cam support, on said holding ring, and on said bearing ring.
