摘要： Disclosed are a reciprocating compressor and a refrigerating apparatus having the same, a ball bearing can be easily stably installed between thrust surfaces of a cylinder block and a crank shaft so as to enhance efficiency of the compressor. Also, a ball bearing can be installed by being inserted into thrust surfaces so as to shorten a moment arm that much, thereby decreasing a frictional loss at a journal bearing surface, resulting in an energy efficiency of the reciprocating compressor and the refrigerating apparatus having the same. In addition, as an oil hole of the crank shaft is veiled by the journal bearing surface of the cylinder block, even if a ball bearing is employed, oil leaked between the thrust surfaces can be reduced, thereby further enhancing the efficiency of the compressor and the refrigerating apparatus having the same.
