Abstract: A rotary compressor, a method of manufacturing a rotary compressor, and an apparatus for manufacturing a rotary compressor are provided. The rotary compressor may include a case having an inner space, a stator to which power may be applied, the stator being disposed in the case, and a compression mechanism disposed on or at one side of the stator to generate a compression force of a refrigerant. The compression mechanism may include a rotational shaft, a cylinder that accommodates a roller coupled to the rotational shaft, a main bearing coupled a first side of the cylinder, and a sub bearing coupled to a second side of the cylinder. The main bearing may be press-fitted and fixed to an inner surface of the case.
