摘要

Disclosed herein is a hermetic compressor including a hermetic container; a rotation drive unit provided at an inner portion of the hermetic container; a rotation shaft combined with the rotation drive unit; a compressor mechanism combined with the rotation shaft to inhale and compress refrigerant; a first bearing fixed to the compressor mechanism to support the rotation shaft; and a second bearing fixed to the hermetic compressor to support an end portion located apart from the first bearing on the rotation shaft, wherein a tolerance (C1) between the second bearing and rotation shaft is 0.55-11.5 times greater than a tolerance (C2) between the first bearing and rotation shaft.
