A double rotary compressor having a bearing with a muffler is provided to reduce the cost and improve the productivity according as the middle bearing divides each compression space and has a muffler function. A double rotary compressor having a bearing with a muffler comprises first and second cylinders(111,121) installed along the shaft direction in a casing(101) to independently form the compression space; upper and lower bearings(112,122) covering the opened side of the outer part of each cylinder to form the compression space with each cylinder; and a middle bearing(140) placed between the cylinders, divides each compression space, and reduces the discharge noise of the refrigerant gas discharged from each compression space. A discharge hole(243) is bored at the main wall of the middle bearing.
