A compressor system includes a pair of compressors located in a common shell. A common drive shaft drives both compressors and the drive shaft is powered by a single motor. One or both of the compressors can be equipped with a pulse width modulated capacity control system and a vapor injection system. When one compressor is equipped with these systems, the capacity can be varied between 50% and 110%. When both compressors are equipped with these systems, the capacity can be varied between 0% and 120%.

A bearing system for a rotor shaft is provided in which a bearing prepared from a high performance polymer is surrounded by an elastomer sleeve that dampens the effect of noise and vibration caused by movement of the rotor shaft against the bearing.
