A hermetic rotary compressor including a housing having an oil sump formed therein; a stationary shaft fixedly mounted in the housing, a longitudinal bore formed in the shaft; and a motor mounted in the housing, the motor having a rotor and a stator, the rotor having a first and second end and being rotatably mounted on the shaft. A pair of compression mechanisms is rotatably mounted on the shaft, the compression mechanisms rotatably coupled to the rotor and lubricated with oil conducted through the longitudinal bore. Each of the compression mechanism has an outboard bearing rotatably mounted on the shaft, and an oil pump in fluid communication with the longitudinal bore is also mounted on the stationary shaft, the pump operatively engaged with one of the outboard bearings. The oil pump is actuated by rotation of one of the outboard bearings, and oil is pumped from the sump into the longitudinal bore by the oil pump.
