Disclosed are a reciprocating compressor and a refrigerating apparatus having the same, a ball bearing (300) can be easily stably installed between thrust surfaces (213, 227) of a cylinder block (210) and a crank shaft (220) so as to enhance efficiency of the compressor. Also, a ball bearing (300) can be installed by being inserted into thrust surfaces (213, 227) so to shorten a moment arm that much, thereby decreasing a frictional loss at a journal bearing surface (215), resulting in an energy efficiency of the reciprocating compressor and the refrigerating apparatus having the same. In addition, as an oil hole (226c) of the crank shaft (220) is veiled by the journal bearing surface (215) of the cylinder block (210), even if a ball bearing (300) is employed, oil leaked between the thrust surfaces (213, 227) can be reduced, thereby further enhancing the efficiency of the compressor and the refrigerating apparatus having the same.
